Monomeric Cu(I) amido, alkoxide, and aryloxide complexes catalyze the addition of N-H and O-H bonds of amines and alcs., resp., to electron-deficient olefins. The ancillary ligands of the active catalysts include the N-heterocyclic carbene (NHC) ligands IPr, IMes, and SIPr {IPr = 1,3-bis(2,6-diisopropylphenyl)-1,3-dihydro-2H-imidazol-2-ylidene; IMes = 1,3-bis(2,4,6-trimethylphenyl)-1,3-dihydro-2H-imidazol-2-ylidene; SIPr = 1,3-bis(2,6-diisopropylphenyl)imidazolidin-2-ylidene} as well as the chelating bisphosphine ligand dtbpe {dtbpe = 1,2-bis(di-tert-butylphosphino)ethane}. For the hydroamination and hydroalkoxylation of olefins, both aromatic and alkyl substituents can be incorporated into the nucleophile, and both primary and secondary amines are reactive. Monosubstituted and disubstituted olefins undergo reaction. For the addition of aniline to acrylonitrile, kinetic studies suggest a pathway that is dependent on the concentration of amine, olefin, and catalyst as well as inversely proportional to the concentration of the product 3-anilinopropionitrile. At low concentrations, the addition of tert-butylisonitrile increases the rate of catalysis. The proposed mechanism involves N-C or O-C bond formation by an intermol. nucleophilic addition of the amido, alkoxide, or aryloxide ligand to free olefin. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Safety of Ethyl 3-ethoxypropanoate).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Safety of Ethyl 3-ethoxypropanoate

Production of aryl oxygen-containing compounds via catalytic pyrolysis of bagasse lignin over La_0.8M_0.2FeO₃ (M=La, Ca, Sr, Ba) was written by Wang, Haiying;Han, Hongjing;Sun, Enhao;Zhang, Yanan;Li, Jinxin;Chen, Yanguang;Song, Hua;Zhao, Hongzhi;Kang, Yue. And the article was included in Journal of Analytical and Applied Pyrolysis in 2019.Recommanded Product: 763-69-9 The following contents are mentioned in the article:

A new method named the production of aryl oxygen-containing compounds via catalytic pyrolysis of bagasse lignin (BL) over perovskites, La_0.8M_0.2FeO₃ (M = La, Ca, Sr, Ba) was proposed. La_0.8M_0.2FeO₃ (M = La, Ca, Sr, Ba) samples were synthesized by the sol-gel method (SG) and characterized by XRD, SEM, BET and XPS, and their catalytic pyrolysis performances were evaluated by the test of TG and the evaluation of the fixed bed microreactor. Under the action of perovskites, the pyrolysis of BL was promoted, the yields of gaseous and solid products decreased while the yield of liquid products increased by 10-20%; decarboxylation and decarbonylation could be inhibited, and it was conducive to the fracture of aliphatic hydrocarbon side chains on aromatic rings, as a result, the selectivity of CO₂/CO decreased while the selectivity of hydrocarbons in gaseous products increased; the total selectivity of aryl oxygen-containing compounds increased from 56 weight% in the liquid product obtained from pure BL pyrolysis to more than 69 weight% in that of catalytic pyrolysis of BL. The spent catalyst was regenerated after controlled combustion of solid product-char, and it showed good structural and catalytic stabilities after 5 successful redox cycles. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Recommanded Product: 763-69-9).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Recommanded Product: 763-69-9

In 1719, Antonio Menzani di Cuna from the Saint Savior monastery published an alc. extract formula made from plant and herb resins under the name Jerusalem Balsam. The Balsam gained high popularity due to its remedial benefits. At the end of the 19th century, Jerusalem Balsam produced by the hermit Johannes Treutler was found to be particularly popular. We analyzed a sample of a valuable find coming from the last decade of the 19th century, making it probably the oldest surviving Jerusalem Balsam in the world. The purpose of this work was to investigate the composition of the historical sample and to try to determine the origin of its components. This was achieved by comparing the profile of volatile compounds extracted from the balsam using HS-SPME technique with the profile characteristic for plant resins as classic ingredients of the Johannes Treutler formula. The use of two chromatog. columns of different polarity, as well as the transformation of the polar components of the sample into TMS derivatives, allowed to obtain new information on the historical composition of the Balsam. Also, it can be stated with high probability that plant resins were indeed used in the production of the Balsam as referred to in the original recipe of Johannes Treutler. We also discuss challenges in determining the original composition of the Balsam.

Renewable and bio-based transportation fuel sources can lower the life-cycle greenhouse gas emissions from vehicles. We present an initial assessment of Et 3-ethoxybutyrate (EEB) as a biofuel in terms of its performance as a fuel oxygenate and its persistence in the environment. EEB can be produced from ethanol and poly-3-hydroxybutyrate, a bacterial storage polymer that can be produced from non-food biomass and other organic feedstocks. Physicochem. properties of EEB and fuel-relevant properties of EEB-gasoline blends were measured, emissions of criteria pollutants from EEB as a gasoline additive in a production vehicle were evaluated, and fate and persistence of EEB in the environment were estimated EEB solubility in water was 25.8 g/L, its K_ow was 1.8, and its Henry’s Law constant was 1.04 × 10^-5 atm-m³/mol. The anti-knock index values for 5 and 20 % volume/volume EEB-gasoline blends were 91.6 and 91.9, resp. Reductions in fuel economy were consistent with the level of oxygenation, and criteria emissions were met by the vehicle operated over the urban dynamometer driving cycle (FTP 75). Predicted environmental persistence ranged from 15 to 30 days which indicates that EEB is not likely to be a persistent organic pollutant. In combination, these results suggest a high potential for the use of EEB as a renewable fuel source.

Solvent Effects in Polyurethane Cure: A Model Study was written by Monaghan, Stephen;Pethrick, Richard A.. And the article was included in Macromolecules (Washington, DC, United States) in 2012.COA of Formula: C7H14O3 The following contents are mentioned in the article:

The effect of change of solvent type on the rate of cure of a polyol with an isocyanate was measured using a range of different techniques. The initial stages of the cure process were followed using viscosity and Fourier transform IR spectroscopy [FTIR] measurements. The gelation point was observed using viscosity measurements and depends on the solvent used. FTIR measurements confirm that both acceleration and inhibition of the polyurethane formation occurs with change of solvent. Comparative studies carried using mixtures of Et acetate/toluene and Bu acetate/xylene are reported. Intrinsic viscosity measurements revealed that the size of the polyol changes with temperature in a different manner depending on the solvent used. In part, the size of the polyol influences the ability for reaction to occur. Measurements of the permittivity, refractive index and solution viscosity indicates that these solvent mixtures deviate from ideality. A model to describe the observed solvent effects is proposed which includes the influence of polarity on the transition state and viscosity on the diffusion of the reactants. Using the measured viscosity and permittivity data for the mixtures, it was possible to obtain a good fit of the exptl. data. This study illustrates how the polyurethane reaction is sensitive to the type of solvent used and indicates how the reactivity may be influenced by change in solvent. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9COA of Formula: C7H14O3).

Influence of nitrogen supply and substrate interactions on the removal of paint VOC mixtures in a hybrid bioreactor was written by Song, JiHyeon;Kinney, Kerry A.;John, Paul. And the article was included in Environmental Progress in 2003.Recommanded Product: 763-69-9 The following contents are mentioned in the article:

The study presented here was designed to investigate VOC degradation patterns as a function of nitrogen availability in a hybrid vapor-phase bioreactor column treating a surrogate paint VOC mixture The mixture consisted of Me Pr ketone, Et 3-ethoxy propionate, Bu acetate, toluene and p-xylene. In order to quantify nitrogen requirements, a series of experiments was conducted under various nitrogen-limited and nitrogen-rich conditions. Overall, increasing nitrogen availability improved the total VOC removal efficiencies from approx. 70% to 99%. At the lowest available nitrogen condition, most of the Et 3-ethoxy propionate and Bu acetate, as well as approx. 75% of the Me Pr ketone were removed in the bioreactor, but toluene and p-xylene were not biodegraded. Increasing the nitrogen availability improved the biodegradation of Me Pr ketone. Substantial degradation of toluene and p-xylene occurred in this study only after the molar ratio of the aromatic compounds to the other constituents in the waste gas stream increased above 2.0. Elimination capacity tests performed with the VOC mixture and each individual VOC indicated that the presence of other VOCs inhibited the biodegradation of toluene and p-xylene. These findings imply that substrate inhibitions limit the removal of aromatic hydrocarbons, particularly when the available nitrogen in the packing media is low.

Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

And the article was included in Journal of Coatings Technology and Research in 2017.COA of Formula: C7H14O3 The following contents are mentioned in the article:

Amphiphilic siloxane-polyurethane (AmSiPU) coatings were prepared using a series of polyisocyanate prepolymers modified with polydimethyl siloxane (PDMS) and poly(ethylene glycol) (PEG). Fouling-release performance of the AmSiPU coatings was evaluated through laboratory biol. assays using several representative marine organisms. First, polyisocyanate prepolymers with compositional variation in PDMS and PEG were synthesized and characterized using Fourier transform IR spectroscopy (FTIR) and isocyanate titrations Then, the prepolymers were incorporated into coatings. Surface wettability of the coatings was evaluated using contact angle and surface energy measurements. Coatings surfaces were also characterized using attenuated total reflectance Fourier transform IR spectroscopy (ATR-FTIR), XPS, and at. force microscopy (AFM). ATR-FTIR and XPS experiments revealed that both PDMS and PEG moieties were present on the surface suggesting amphiphilic character. AFM phase images show microphase separation AmSiPU coatings show excellent fouling-release performance toward bacteria (Cellulophaga lytica), the diatoms (Navicula incerta), and the green algae (Ulva linza), demonstrating comparable or superior performance to many com. amphiphilic fouling-release coatings. Despite the incorporation of hydrophilic PEG, AmSiPU coatings show good macrofouling release which is often challenging with amphiphilic coating systems.

Effect of liquid properties on curtain stability in low flow rate was written by Furukawa, Hiroyasu;Kanai, Hiroshi;Nagase, Magonori;Kobayashi, Ryoji;Alleborn, Norbert. And the article was included in ISIJ International in 2013.Recommanded Product: Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

Curtain coating, which can achieve very high speed coating and smooth film without defects, is recently used to produce pre-painted steel sheets for home appliances and utensils. One of the difficulties limiting curtain coating operation arises from a low limit in flow rate, below which the falling liquid sheet breaks apart and we can not operate. We measured the min. flow rate for curtain formation for polyester resin solutions in very low Reynolds number (Re) exptl., and found that the min. flow rate decreased with decreasing surface tension and d., and with increasing viscosity of the liquids Relationship between the phys. properties of the liquids and the min. flow rate for curtain formation (curtain stability) was analyzed by using Reynolds number (Re) which represented the flow rate and Phys. property number (Ka) which included surface tension, viscosity and d. As a result, the calculating formula by which the min. flow rate can be estimated was given. Further more, effects of surfactant on the min. flow rate were studied. It is suggested that homogeneity of the surface is very important to stabilize the curtain, and if we use surfactants which decrease surface tension of the liquids uniformly, the curtain stability increases. In the range of this study, curtain stability is mainly dominated by liquid properties, and neither edge guides nor disturbances like bubbles in the liquids seem key factors for curtain stability.

Antiobesity Effect of Oil Extract of Ginseng was written by Kim, Hyo Jung;Kang, Hui Jung;Seo, Ji Yeon;Lee, Choong Hwan;Kim, Young-Suk;Kim, Jong-Sang. And the article was included in Journal of Medicinal Food in 2011.Reference of 763-69-9 The following contents are mentioned in the article:

In a preliminary study we found that incubating raw ginseng in oil facilitated autolysis and extensive metabolism of ginseng, releasing flavor and lipophilic compounds into the oil so that it could be used as an ingredient for high value-added foods, while the residue could be utilized for making ginseng extract Here, we report the effect of oil (grape seed oil [GSO]) extract of ginseng (OEG) on body weight gain and lipid metabolism in a mouse model. OEG, but not GSO, inhibited porcine pancreatic lipase. Plasma triglyceride (TG) levels were lower in male ICR mice at 1, 2, 3, and 4 h after oral administration of the lipid emulsion plus OEG (1 g/kg of body weight) than in the group administered only the lipid emulsion or lipid emulsion plus GSO. Next, male C57BL/6J mice were fed a standard diet, a high fat (HF) diet containing 30% lard, or diets including 30% OEG or GSO based on the standard diet for 14 wk. Consumption of OEG-containing diet significantly lowered the body weight gain, feed efficiency, visceral fat accumulation, plasma TG, and hepatic and white epididymal adipocyte sizes, as well as expression of peroxisome proliferator-activated receptor γ (PPARγ) in liver and adipose tissue. In conclusion, dietary OEG improved obesity-related parameters in blood, liver, and adipose tissue in a mouse model and suppressed obesity induced by HF diet, possibly by regulating lipid metabolism by modulating PPARγ protein expression.
