摘要
Abstract
The key process in the synthesis of vitamin D3 is the photochemical conversion from 7-dehydrocholesterol to pre-vitamin D3,which is currently carried out in batch photoreactors and suffers from low conversion efficiency,recycle of unreacted 7-dehydrocholesterol,and long production period.Using micro-flow photoreactor instead of batch photoreactor,the conversion yield of 7-dehydrocholesterol may be increased from less than 30% to over 95%,allowing the photoreaction product to be directly used to prepare resin-like vitamin D3 through a thermal isomerization reaction and shortening the production period greatly.关键词
