摘要
经典的 Reimer- Tiemann(简称 R- T)反应主要产物为邻位羟基取代苯甲醛类化合物 ,对位羟基取代苯甲醛类化合物为次要产物 ,其量甚少。用β-环糊精催化 Reimer- Tiemann反应时 ,对位选择性可达 1 0 0 %。本文研究了用 β-环糊精交联树脂催化合成对羟基苯甲醛的工艺方法。通过正交实验确定了最佳工艺条件。
The main production of Reimer-tiemann reaction were orhohydrony replace benziocaidenhyde.Under the catalysis of immobilized β-CD,selectivity of conter-hydronylate replacing benzoicaidenhyde were 100%.In the paper the technology for preparation of 4-Hydroxybenzaldenhyde were sutdied and the optimun conditions were definited.
