ALCOHOL-ESTER SEPARATION BY REACTION WITH ACETATEThe invention relates to a process for separating an enantiomerically enriched alcohol from a first mixture of 1-arylsulfonate-2-hydroxy-3-butene and enantiomerically enriched 1-arylsulfonate-2-acyloxy-3-butene enriched enantiomerically. The method ...

The meaning of ESTER is any of a class of often fragrant organic compounds that can be represented by the formula RCOOR' and that are usually formed by the reaction between an acid and an alcohol with elimination of water.
a chemical compound produced by the reaction between an acid and an alcohol with the elimination of a molecule of water, as ethyl acetate, C4H8O2, or methyl methacrylate, C5H8O2. [1850–55; < German (1848), probably b.Essigvinegar andӒtherether] ...

A method for the production of (meth)acrylate esters (I) by reacting (meth)acrylic acid (II) with alcohols (III) in presence of zeolite(s), in which the zeolite has pore openings of 4-8 and a silica/(aluminum, boron or iron oxide) mol ratio of 12-40, and the reaction is carried...
the esterification reaction between acid and alcohol is reversible: (1) If the ester content in the new liquor is high (e.g., ethyl acetate), the ester will undergo volatilization and hydrolysis, and the amount of ester will be reduced so that the esterification reaction can reach a balance...
HA esters are prepared by the reaction of the quaternary ammonium salt of HA with an alcohol that imparts hydrophobicity, using a non-aqueous solvent such as dimethylformamide for the reaction (Campoccia et al., 1998). For example, the benzyl ester HYAFF-11 (Fidia Advanced Biopolymers) is ...
An ester is a chemical compound derived from an acid (organic or inorganic) in which at least one –OH hydroxyl group is replaced by an –O– alkyl (alkoxy) group, as in the substitution reaction of a carboxylic acid and an alcohol. Glycerides are fatty acid esters of glycerol; they are...
