摘　　要：以4，4＇-二胺基二苯基甲烷和顺丁烯二酸酐为原料，采用均相体系、共沸蒸馏的方法，一步合成了N,N＇-4，4＇-二苯甲烷双马来酰亚胺（BMI），收率为86％。并用高效液相色谱测定出产物的相对含量为98．3％，用红外光谱表征了产物的分子结构，用毛细管法测定了产物熔点为158～160℃.The synthesis of N, N＇- （4,4＇-diphenylmethane） bismaleimide （BMI） was carried out by onestep procedure which comprises the reaction of 4,4＇-Diaminodiphenylmethane and maleic anhydride in homogenous phase and eliminates the formed water through azeotropic distillation. The yield of BMI reaches 86% by weight and its purity is found to be 98.3% by high performance liquid chromatography（HPLC）. The molecular structure of BMI was characterized by FTIR and its melting point measured by capillary tube method is 158-160℃.
