摘要
通过酸处理活性碳催化环氧苯乙烷制备苯乙醛 ,收率可达 97.5 %。并筛选了缩合反应催化剂 ,以三乙醇胺为催化剂实现了苯乙醛与海因的直接缩合。 5 -苯乙叉基海因收率 5 0 %
Phenylacetalhyde was obtained from styrene oxide under inorganic acid-treated active carbon as a catalyst. The yield of Phenylacetalhyde was 97.5%. Triethanolamine was found directly to be able to catalyze the condensation of phenylacetaldhyde and hydantoin. The yield of. 5-(2-phenylethylidine) hydantoin was over 50%.
