| 摘 要： | 本文从减少副反应的角度出发，改变了Ｒｅｉｍｅｒ－Ｔｉｅｍａｎｎ反应操作中氢氧化钠溶液的加入方式，用过量的氯仿作溶剂，以三正丁胺为相转移催化剂，通过由本酚制备水杨酸的实验，研究了催化剂、氯伤和氢氧化钠用量以及反应时间对水杨醛产率的影响，水杨酸的产率达５８％．

| Abstract: | In order to reduce the secondary reections,the adding method of sodium hydroxide solution was changed in Reliner-Tiemann reaction. The preparation of salicylal from phenol was conducted with the excessive chloroform as solvent and the tri-n-butyl amine as a phase transfer catalyst. The effects of the emount of catalyst,chloroform,sodium hydroxide and the reaction time on the yield of salicylal were studied. The yield of salicylal was reached to 58%. |
