Enzyme-catalyzed process for the preparation of macrocyclic polyester oligomers

摘要

A process for the enzyme-catalyzed preparation of cyclic ester oligomers from dicarboxylic acids and/or dicarboxylic acid derivatives and diols, hydroxycarboxylic acids and/or hydroxycarboxylic acid esters, and/or linear ester oligomers in the presence of a solvent comprising a tertiary alcohol and a non-alcoholic solvent.
