Abstract:
1. A process comprising contacting in a reaction mixture a propylene glycol ether racemate of formula II where R is selected from an alkyl selected from CH 3 , CH 3 CH 2 , CH 3 (CH 2 ) 2 , CH 3 (CH 2 ) 3 and C(CH 3 ) 3 , or aryl group; where the racemate is at a concentration of at least 5% v/v; and where the reaction mixture further comprises an acyl donor which is an activated acyl donor selected from the group consisting of an enol ester; with an effective amount of an enzyme catalyst hydrolase whereby an enantiomer of the racemate is enantioselectively transesterified to a corresponding enantiomer of acylated propylene glycol ether where the racemate, the acyl donor, and the enzyme catalyst hydrolase comprise 100% v/v of the reaction mixture.
