Provided are an epoxy compound of high-purity N,N,N',N'-tetraglycidyl-3,4'-diaminodiphenyl ether and a method for producing the same. High-purity N,N,N',N'-tetraglycidyl-3,4'-diaminodiphenyl ether is produced by: an addition reaction step of reacting 3,4'-diaminodiphenyl ether with epichlorohydrin in a polar protic solvent at 65 to 100°C for 12 hours or longer to form N,N,N',N'-tetrakis(3-chloro-2-hydroxypropyl)-3,4'-diaminodiphenyl ether; and a cyclization reaction step of reacting the N,N,N',N'-tetrakis(3-chloro-2-hydroxypropyl)-3,4'-diaminodiphenyl ether with an alkali compound for dehydrochlorination.
本文提供了一种高纯度 N,N,N',N'-四缩水甘油-3,4'-二氨基二苯醚环氧化合物及其生产方法。高纯度 N,N,N',N'-四raglycidyl-3,4'-diaminodiphenyl ether 是通过以下方法生产的:加成反应步骤:3,4'-二氨基二苯醚与环氧氯丙烷在极性原溶剂中于 65-100°C 下反应 12 小时或更长时间,生成 N,N,N',N'-四(3-氯-2-羟基丙基)-3,4'-二氨基二苯醚;环化反应步骤:将 N,N,N',N'-四(3-氯-2-羟基丙基)-3,4'-二氨基二苯醚与碱化合物进行脱氢氯化反应。
