Plastisol viscosity reduction and control is an important property specification in many vinyl plastisol formulations. 2-Ethylhexyl benzoate plasticizer is under development that functions as a viscosity reducer for PVC. It also is a highly solvating plasticizer in standard plastisol systems. Data are presented on the effects of the new benzoate plasticizer on the properties of phthalate- and benzoate-containing plastisols and vinyl sheet for flooring. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Application In Synthesis of 2-Ethylhexyl benzoate).

2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Application In Synthesis of 2-Ethylhexyl benzoate

Catalytic Enantioselective Addition of Diethylzinc to Trifluoromethyl Ketones was written by Yearick, Kimberly;Wolf, Christian. And the article was included in Organic Letters in 2008.Computed Properties of C11H9F3O3 The following contents are mentioned in the article:

A procedure for nucleophilic addition of diethylzinc to trifluoromethyl ketones was developed. The TMEDA-catalyzed method converts aromatic substrates to the corresponding 2-aryl-1,1,1-trifluorobutan-2-ols in up to 99% yield, and it is also applicable to less reactive aliphatic ketones if stoichiometric ligand amounts are employed. The first asym. variant producing tertiary alcs. with up to 61% ee when TBOX is used as catalyst is described. This study involved multiple reactions and reactants, such as Ethyl 4-(2,2,2-Trifluoroacetyl)benzoate (cas: 898787-14-9Computed Properties of C11H9F3O3).

Ethyl 4-(2,2,2-Trifluoroacetyl)benzoate (cas: 898787-14-9) 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. 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.Computed Properties of C11H9F3O3

A phosgene-free synthesis of sym. bis(polyfluoroalkyl) carbonates H(CF₂CF₂)_nCH₂OC(O)COCH₂(CF₂CF₂)_nH (n = 1, 2, 3) involves the transesterification of di-Ph carbonate with polyfluoroalkanols H(CF₂CF₂)_nCH₂OH promoted by stoichiometric amounts of titanium(iv) alkoxides Ti(OR)₄ (R = Et, n-Bu, i-Pr). This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Recommanded Product: Diphenyl carbonate).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Recommanded Product: Diphenyl carbonate

Integrated chemical process: an extremely concise synthesis of vitamin A was written by Orita, Akihiro;Yamashita, Yasuo;Toh, Akiji;Otera, Junzo. And the article was included in Angewandte Chemie, International Edition in English in 1997.Formula: C12H18O3 The following contents are mentioned in the article:

A one-pot procedure conducted stepwise under basic conditions gave an improved yield via an integrated chem. process. Lithium salt of a cyclogeranylsulfone treated with a dimethyloctadienal gave the addition product I which was converted to the MOM ether, underwent double elimination when exposed to MeOK to yield vitamin A. Addition of cyclohexane as a cosolvent in the elimination step increased the yield slightly. This study involved multiple reactions and reactants, such as (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5Formula: C12H18O3).

(2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5) 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. 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. Formula: C12H18O3

(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. 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.Quality Control of (E)-Dodeca-9,11-dien-1-yl acetate
