摘要
以表面经偶联剂修饰的二氧化硅为载体 ,通过聚 (β-氯乙基缩水甘油醚 )和醇钠反应 ,合成了两种梳状聚醚三相转移催化剂 ,研究了它们在碘代、二氯卡宾对双键加成和混合醚制备反应中的催化活性。结果表明 。
Two triphase catalysts of comb-like polyethers supported by silicas were synthesized,and their catalytic behavior in the iodo-substitution,etherization and the addition reaction of dichlorocarbene to styrene were also studied.The results show that the triphase catalysts exhibit excellent catalytic activity and reusability.
