PROCESS FOR MAKING ESTERS OF 2-ACETOXYALKANOIC ACIDS USING A 3,6-DIALKYL-1,4-DIOXANE-2,5-DIONE OR POLY-(ALPHA-HYDROXYALKANOIC ACID) AS A STARTING MATERIAL

2-Acetoxyalkanoic acid esters are made in a reaction of a 3,6-dialkyl-1,4-dioxane-2,5-dione or a poly(α-hydroxyalkanoic acid), an acetate ester and an alcohol or phenol in the presence of a transesterification catalyst. Unlike previous methods for making 2-acetoxyalkanoic acid esters, this process proceeds in high yield and high selectivity to the desired product.

LACTATE PRODUCTION PROCESS

A process for producing a compound of formula (I) is provided. The process comprises reacting a mixture comprising a compound of formula (IIA) and a compound of formula (IIB) with an alkyl alcohol in the presence of a Candida antarctica lipase B enzyme to produce a product comprising the compound of formula (I) and the compound of formula (IIB); wherein R1 is C1 to C6 alkyl; and wherein R2 is H or C1 to C12 alkyl. Also provided are processes for the production of R-lactic acid, oligomeric R-lactic acid, R,R-lactide, poly-R-lactic acid, alkyl S-lactate, S-lactic acid, oligomeric S-lactic acid, S,S-lactide, poly S-lactic acid and stereocomplex polylactic acid.
