A N, inter-N' - phenylene bismaleimide preparation method

-

Paragraph 0027, (2019/07/04)

The invention discloses a N, inter-N' - phenylene bismaleimide preparation method, which belongs to the technical field of fine chemicals. The raw material is toluene, maleic anhydride and the polymerization inhibitor, heated to 40 - 60 °C dissolve; the metaphenylene diamine dissolved in strong polar solvent then drop added in a reaction vessel, and milling after thermal insulation, adding catalyst heating temperature to reflux, until no more water is stopped when the reaction is separated out; the reaction cooling after crystallization, filtered, washed with water, to obtain pale yellow solid N, between the N' - phenylene bismaleimide. The invention two-step reaction in the same reaction in the container, does not need to separation and purification of the intermediate product, its synthesis process is simple in operation, the working environment is obviously improved. The sold product liquid chromatography the content of 75% -80%, for the production of this invention liquid chromatography content can be up to 90% or more, the purity is higher than current commercial products.

Paragraph 0016; 0017; 0018; 0019; 0020; 0021; 0022-0030, (2017/05/10)

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.
