Abstract
Glycol ether acetates, and in particular propylene glycol alkyl (or aryl) ether acetates, can be resolved enzymatically by enantioselective hydrolysis with a hydrolase at high concentrations of substrates; in some embodiments, the hydrolase is a lipase. Glycol ethers, and in particular propylene glycol alkyl (or aryl) ethers, can be resolved enzymatically by enantioselective transesterification with a hydrolase, in the presence of an acyl donor, at high concentrations of substrates; in some embodiments, the hydrolase is a lipase.
