Abstract
The preparation of racemic or enantioenriched propane-1,2-diol from dilactides, oligolactides, or poly-L-lactic acid (PLLA) is described. The transformation is carried out as tandem reactions in MeOH, covering hydrolysis and subsequent hydrogenation by using copper chromite as a catalyst. The starting material present undesired side products of the PLLA synthesis or PLLA waste.
摘要
描述了从丙交酯、低聚物丙交酯或聚 L-乳酸（PLLA）制备外消旋或对映体富集的 1,2-丙烷二醇。该转化在 MeOH 中作为串联反应进行，包括水解和随后的氢化，使用铜铬绿作为催化剂。起始材料为 PLLA 合成或 PLLA 废料中的不需要的副产物。
