N,n’-间苯撑双马来酰亚胺及其制备方法

N,N'-m-phenylenedimaleimide and preparation method thereof

Abstract

The invention provides a preparation method of a multifunctional rubber vulcanizer N,N'-m-phenylenedimaleimide under the condition of no acetic anhydride. M-phenylenediamine, cis butenyl maleic anhydride, toluene and ethyl acetate are used as raw materials to synthesize the N,N'-m-phenylenedimaleimide. The reaction process is simple and does not need acid anhydride or any other catalyst; and the obtained product has high purity.
本发明提供了一种多功能橡胶硫化剂N,N’-间苯撑双马来酰亚胺无乙酸酐存在下的制备方法。该制备方法采用以间苯二胺、顺丁烯马来酸酐、甲苯、乙酸乙酯为原料,合成了N,N’-间苯撑双马来酰亚胺,其反应过程简单,无需酸酐等催化剂,得到产品的纯度高。
