Abstract
The method of preparation of N,N’-m-Phenylenedimaleimide by the reaction of maleic anhydride with m-phenylene-diamine in acetic acid was studied.The optimum condtions were found out by orthogonal experimental design.Qualitative analysis and quantitative analysis were carried out by melting point determination meter,infrared spectrometer and high performance liquid chromatograph.The results show that the reaction is easily manageable when the weight of acetic acid is 3 times that of m-phenylene-diamine.The mole ratio of catalyst to m-phenylene-diamine is 0.05 to 0.3.the maleic anhydride to m-pheny-lene-diamine mole ratio is 2.1:1.The yield is 90.2% in the optimum condtions.The infra-red spectrogram of the product conforms to the standard.The content of the product is 96%.
