摘要
研究了愈创木酚与氯仿在β CD催化下选择合成香兰素 .实验结果表明 ,其对位选择性高达 1 0 0 % .β CD交联树脂作催化剂可反复使用 。
The selective synthesis of vanillin from Guaiacol an d Chloroform using and immobilized β -Cyclodextrin as catalyst is described in this paper. The selectivity is as high as 100%. The reaction was carried out at 65℃ for 4 hrs. β -CD epichlorohydrin crosslinked resins used as catalyst i s recoverable and reusable without decreasing selectivity and yield.
