以邻氯对苯二酚、环氧氯丙烷为原料,四乙基溴化铵为相转移剂,在碱性条件下,合成邻氯对苯二酚二缩水甘油醚。最佳合成条件:n(环氧氯丙烷)∶n(邻氯对苯二酚)为18,x(催化剂)为1.0%,闭环反应4 h最高收率可达80.5%。通过傅里叶红外光谱仪和显微熔点测定仪对产物结构和熔点进行了表征,并计算出该产物与甲基四氢苯酐(Me–THPA)的固化体系的活化能。
Using o-chlor hydroquinone and epichlorohydrin as raw materials and tetraethylammonium bromide as phase transfer agent, o-chloro hydroquinone diglycidyl ether was synthesized under basic condition. The optimal synthesis conditions were as follows: n (epichlorohydrin): n (o-chloro hydroquinone) was 18, x (catalyst) was 1.0%, the highest yield of closed- The structure and melting point of the product were characterized by Fourier transform infrared spectroscopy (FT-IR) and micro melting point analyzer. The activation energy of the product was also calculated with the curing system of methyl tetrahydrophthalic anhydride (Me-THPA).
