对叔丁基杯[4]芳烃及其醚类衍生物的合成
Synthesis of p-tert-Butylcalix[4]arene and Ether Derivative
摘要
Abstract
p-tert - Butylcalix[4]arene was synthesized by p - tert - butylphenol and aldehyde using alkali as catalyst. An appropriate amount of ethyl acetate was added as a water carrier and the diphenyl ether was recycled as solvent. Amount of ethyl acetate and recycle times of diphenyl ether which effect on the yield of product were investigated. The results show that the addition of ethyl acetate can make the products yield increase, the dehydration time shorten and the reaction control easily. Recycle times of diphenyl ether has significant effect on the products yield. The yield increased to 73 % when diphenyl ether was reused 3 times. The improved method can shorten reaction time and increase the yield of products. In addition, the effect of the catalyst K2CO3 amount on the yield of tetraethyl p- tert- butylcalix[4]arene tetraacetate were discussed. The result shows that the yield of the product can reached 74% when the optimal mole ratio of p - tert - butylcalix[4]arene to catalyst K2CO3 was 1 : 11.关键词
