摘要

Candida antarctica lipase B (CAL-B, Novozyme 435) catalyzes the transacylation of methyl acrylate and methyl methacrylate with diols and triols in 2-methyl-2-butanol at 50° C. Under the experimental conditions, up to 70mol% of the acyl donor methyl acrylate was converted. Methyl methacrylate is the less efficient acyl donor (up to 60mol%) due to the higher sterical hindrance in the enzymatic transacylation. Under the reaction conditions high yields of the ...
