Verfahren zur selektiven Veresterung von Polyolen |
摘要 |
<p>The invention relates to the production of polyoles from corresponding polyoles and carboxylic acids containing an aromatic ring, whereby said polyoles are esterified on the primary OH-group. The aim of the invention is to improve the selectivity and yield without introducing or separating protective groups. The polyole is reacted with a carboxylic acid alkyl ester in the presence of an organic solvent and under catalysis of a hydrolase, especially lipase or esterase.</p> |
