Zharova, P. A. published the artcileOriginal Pt-Sn/Al2O3 catalyst for selective hydrodeoxygenation of vegetable oils, Name: Benzyl acetate, the main research area is platinum aluminum oxide catalyst hydrodeoxygenation vegetable oil.

The preparation of biodiesel from fatty materials HDO provides a very constructive idea to solve the global clean energy problem. The application of catalytic technol. to convert oils into green liquid hydrocarbon fuel has great potential for industrial application. The main problem with the development of green diesel technol. is the limited number of available non-food sources of fatty acid triglycerides. Also the researchers have made remarkable achievements in the field of catalyst, the stability of the catalyst is insufficient and the selectivity of large mols. of direct alkanes is low. These defects hinder the large-scale resource development of biodiesel. In current paper the potential of hydrodeoxygenation (HDO) of fatty materials and model esters was explored by enhancing the synergy of platinum and tin by using heterometallic (PPh4)3 [Pt (SnCl3)5 complex. Heterometallic (PPh4)3 [Pt (SnCl3)5] complex provides in its structure platinum and tin atoms linked by a metal-metal bond that causes the originality of catalytic performance. The performance of bimetallic Pt-Sn/Al2O3 catalyst, which is characterized by the Sn/Pt molar ratio of 5/1, has been studied at hydrogen pressure 50 atm and temperature 400-480°C. HDO reaction of a number of fatty materials has been shown to proceed with the highest ever yield of direct hydrocarbons derived from alkoxy and acyl groups of the initial ester. Also it was investigated a performance in HDO reaction of mixture containing rapeseed oil oleic acid and water that simulate cooked oil that may be a prospective soure for green hydrocarbons in megalopolises. A structural studies of the catalyst showed that its high selectivity in HDO reaction of fatty materials provided by two important factors: impregnated particles size and formation of intermettallic species of PtSn3±σ. Finally, catalysts sustained activity and stability were tested during five turns of 24 h each.

He, Zhiwei published the artcileEncapsulation of heteropolyacids within hollow microporous polymer nanospheres for sustainable esterification reaction, Product Details of C9H10O2, the main research area is heteropolyacid microporous polymer nanosphere catalyst esterification reaction.

Herein, the Keggin structural phosphotungstic acid (HPW) has been successfully encapsulated within hollow microporous polymer nanospheres (H-MPNs) by a “”ship-in-bottle”” approach. The H-MPNs are formed by self-assembly induced by hyper-crosslinking of polylactide-b-polystyrene (PLA-b-PS). The obtained catalysts (HPW@H-MPNs) exhibit more sustainable availability than the previously reported HPW-supported catalysts in esterification reaction. This excellent sustainability can be attributed to the stable microporous channels in H-MPNs which are smaller than the mol. size of HPW, thereby effectively preventing the HPW from leaking out. Moreover, such catalysts also perform well in terms of catalytic activity and universality because of the combination of a hollow structure in the interior and permeable pore channels in the shells. This type of polymer carrier and general encapsulation method may provide a new strategy for developing more sustainable catalysts for various chem. reactions.

Al Farraj, Dunia A. published the artcilePolynuclear aromatic anthracene biodegradation by psychrophilic Sphingomonas sp., cultivated with tween-80, Quality Control of 140-11-4, the main research area is polynuclear aromatic anthracene Sphingomonas tween 80 biodegradation; Anthracene; Optimization; PAHs; Sphingomonas; Tween-80.

Anthracene is a low mol. weight polynuclear aromatic hydrocarbons (PAHs) being identified as a precedence toxic contaminant in the ecosystem. Thus, the present work was designed to evaluate anthracene biodegradation efficiency by selected marine bacteria. From the marine isolates, the most effective anthracene biodegrading strain was identified as Sphingomonas sp., KSU05. Time course batch growth results indicated that the isolate KSU05 was capable of surviving up to 500 mg/L of anthracene. The influence of various nutrient sources were screened for enhanced growth and pyrene degradation, based on results glucose and tween-80 were used for further optimization studies. Batch exptl. anal. showed maximum biodegradation (70.5%) of anthracene (50 mg/L) with enhanced survival of Sphingomonas sp. KSU05 was observed at 96 h of cultivation. Box-Behnken design optimization results showed that the culture conditions enhanced the anthracene biodegradation (90.0%) at pH 7.0, 0.3 mM of tween-80 concentration, and 5.5% of glucose concentration In addition, the isolate Sphingomonas sp. KSU05 was found to rapidly degrade anthracene within 96 h. The anthracene intermediates was analyzed using Gas chromatog. mass spectrophotometer (GC-MS). Overall, this research shown that the Sphingomonas sp., cultivated with suggested optimum conditions could provide an effective prospective for the degradation of anthracene from contaminated environment.

Grinan, I. published the artcileVolatile composition and sensory and quality attributes of quince (Cydonia oblonga Mill.) fruits as affected by water stress, Computed Properties of 140-11-4, the main research area is volatile compound food quality water deficit Cydonia.

No information exists on the effect of water deficit on quince (Cydonia oblonga Mill.) fruit quality characteristics. In this paper, the effect of withholding irrigation water in the middle of the rapid fruit growth period on yield, main fruit physicochem. characteristics, sensory profile, and volatile composition of quince (cv. BA-29) was studied. The linear fruit growth phase was seen to be a critical phenol. period for the marketable yield of quince because water deficit decreased the fruit weight, size, and moisture content. Also, this period was clearly critical for the fruit’s chem. characteristics. Water deficit induced important changes in an important number of the identified volatile compounds, characterized by decreases on pear, pineapple and apple sensory descriptors and increases on the green-herbaceous sensory descriptors. Moreover, total soluble solids increased and the total polyphenols content and antioxidant activity decreased as a result of water deficit effect, even though the still high levels of total polyphenols, regardless of the fruit water status, suggested that quinces can be used as an important source of natural antioxidants. The fruit sensory anal. indicated that the peel color intensity of fruits from the water deficit treatment increased and fruit flesh texture improved. Indeed, the main handicaps for its consumption as fresh fruit (corkiness and fiberness) severely decreased and crunchiness increased.

Zhang, Ning published the artcileChanges of amygdalin and volatile components of apricot kernels during the ultrasonically-accelerated debitterizing, Related Products of esters-buliding-blocks, the main research area is amygdalin apricot kernel ultrasonic debitterizing; Amygdalin; Apricot kernels; Debitterizing; Epimerization; Volatile components.

Ultrasound has been regarded as an efficient novel technique for debitterizing of the apricot kernels, but its influence is severely concerned on the possible epimerization of D-amygdalin to the L-amygdalin, a more potentially toxigenic compound Considering this, the experiments were conducted to investigate the epimerization of D-amygdalin and the volatile components in the debitterizing water, which were separated and identified by the high performance liquid chromatog. (HPLC) and gas chromatog. with a mass spectrometer (GC-MS), resp. The results indicate that the ultrasonically-debitterizing did not cause the epimerization of D-amygdalin to the L-amygdalin, while the procedure can be greatly accelerated due to the rapid mass transfer and degradation of D-amygdalin induced by ultrasound irradiation In addition, the water from the ultrasonically-debitterizing of apricot kernels exerted more aromas compared with that of the conventional debitterizing, which might have more applications about this kind of water. In a word, ultrasound can be safely applied in the debitterizing industry of apricot kernels.

Shi, Gui Min published the artcileTwo-membrane air fresheners for continuous non-energized perfume delivery, Formula: C9H10O2, the main research area is two membrane air freshener nonenergized perfume delivery.

We have developed two-membrane air fresheners for continuous non-energized air freshener perfume delivery with significantly superior delivery consistency over a conventional membrane air freshener. In this study, a model perfume is used to investigate the conventional air freshener as functions of temperature and air velocity. The release rate of the conventional air freshener varies greatly from its initial use to its end-of-life under a fixed ambient condition. In order to regulate the evaporation rates of the volatile compounds, the new air freshener consisting of an inner membrane and an outer membrane. The outer membrane is used as the regulation membrane to create a vapor reservoir between the inner wet membrane and the outer membrane so that the vapor generated from the inner membrane can be regulated. Comparing the conventional air freshener to the new air freshener, the outer membrane impregnated with polyethylene glycol (PEG) shows significantly better consistency of perfume delivery rates under different air velocities and temperatures In addition, a model has been employed to predict the perfume release from the conventional air freshener. The perfume release from the newly developed air fresheners is regulated by vapor transport through the outer membrane which may be predicted through the Knudsen flow or solution diffusion model.

Zhang, Jingying published the artcileIdentification of Key Aroma Compounds in Cranberry Juices as Influenced by Vinification, Recommanded Product: Benzyl acetate, the main research area is cranberry juice vinification aroma compound; GC−MS/O; PCA; SPME; aroma-active; cranberry wine; volatile compounds.

This study aimed to identify the key aroma-active volatiles in cranberry wines through three vinification methods (White, Red and Thermo) using GC-MS/O to identify the important aroma compounds A total of 70 compounds were detected, with 67 in wines and 61 in juices. The esters was the most diversified class, while alcs. and acids were the most abundant, especially 3-methylbutanol, methylbutyric acid, and benzoic acid. The volatile profiles of cranberry wines are distinctive from their source juices. Most alcs., esters, and acids are fermentation-derived, while terpenes, phenols, aldehydes and ketones are varietal. The Red vinification retained the most varietal volatiles from the must, while the White and Thermo vinifications produced more volatiles during fermentation Thermovinification reduced the yield of benzoic acid and its derivatives after fermentation Olfactory anal. identified 47 aroma-active compounds, among which 41 were considered as the major aroma contributors (Et benzoate had the highest modified detection frequency).

Sandeepa, Kadakanchi published the artcileDetermination of Solid-Liquid Phase Equilibrium of Benzoic Acid in Mono, Binary, and Ternary Systems and Their Correlation, Safety of Benzyl acetate, the main research area is solid liquid phase equilibrium benzoic acid; mono binary ternary system correlation.

The present research work has evaluated the equilibrium solubility data of benzoic acid in monosolvents (benzyl acetate and benzyl benzoate), in binary systems (benzyl alc. + toluene), (benzyl acetate + toluene), and (benzyl benzoate + toluene) at 288.15-328.15 K, and in ternary systems (benzoic acid + phthalic acid + benzyl alc./methanol) at two different temperatures 298.15 and 308.15 K by varying the mole fraction of the binary mixture using high-performance liquid chromatog. Solid-liquid phase equilibrium data for the ternary system were measured using the isothermal saturation method and the ternary solubility data (saturated liquid and wet solid phase) were used to construct the isothermal phase diagrams. The two pure solids formed in the ternary system were distinguished by Schreinemaker’s wet residue method at the corresponding temperatures The exptl. solubility data of benzoic acid in monosolvents and binary systems from this work were fit to various thermodn. models reported in the literature such as the Buchowski equation and the Jouyban-Acree model. The Wilson model was also fit to investigate the effect of binary interaction parameters on the solubility of ternary systems. The exptl. solubility data of benzoic acid in the solvents were in good agreement with the calculated values obtained through the thermodn. models. The solubility data and phase diagram for the ternary systems show more practical application for the obtained benzoic acid and phthalic acid pure regions. For the ternary system that consists of methanol, pure regions were larger compared to that of the system with the benzyl alc. as a solvent. Thus, the Wilson model was successful in explaining the exptl. phase behavior of the ternary system, which was reflected in the min. root-mean-square deviation value of 0.0086 for methanol at 298.15 K.

Huang, Yaling published the artcileVariation of Volatile Compounds and Corresponding Aroma Profiles in Chinese Steamed Bread by Various Yeast Species Fermented at Different Times, Application of Benzyl acetate, the main research area is volatile aroma Chinese steamed bread yeast; Chinese steamed bread; GC−MS; GC−O; aroma-active compounds; sensory evaluation.

To control the fermentation process of yeast-Chinese steamed bread (CSB), the volatile compounds and odor profiles of yeast-CSBs during fermentation were comprehensively investigated by sensory evaluation, gas chromatog.-mass spectrometry, gas chromatog.-olfactometry (GC-O), and odor activity value (OAV). Eight sensory attributes were established, and quant. descriptive anal. results showed that CF1303-CSB had intense sweet and sweet aftertaste attributes, CF1318-CSB was characterized by milky, wheaty, and yeasty attributes, while CL10138-CSB presented distinct sour, winy, and floury attributes. A total of 41 key aroma-active compounds were detected, and phenylethyl alc. was the most potent aroma compound with a flavor dilution (FD) of 1024. CF1303-CSB, CF1318-CSB, and CL10138-CSB contained 24, 22, and 21 key aroma compounds, resp., based on the OAV. These key aroma compounds can be used as the potential markers to monitor the yeast-CSBs during the fermentation process. Five compounds, including β-myrcene, 2-phenoxyethanol, Me cinnamate, guaiacol, and o-cresol, were first identified in CSB. These results provide theor. basis for processing and quality control of yeast-CSBs.
