METHOD OF OBTAINING N-(4-PHENYLAMINOPHENYL)MALEINIMIDE Russian patent published in 2015 - IPC C07D207/12 

Abstract RU 2547727 C2

FIELD: chemistry.

SUBSTANCE: invention relates to obtaining N-(4-phenylaminophenyl)maleinimide, which can be used as a chemical multipurpose modifier for rubber mixtures, as well as in the production of thermally resistant polymers. The method includes the interaction of maleic anhydride with 4-aminophenylaniline in an acetone medium, separation of an intermediate amide from the acetone solution by its filtration in vacuum and air-drying for 24 hours, with further dehydrocyclisation of the separated amide by boiling in a toluene and dimethylformamide mixture in the presence of toluenesulphonic acid.

EFFECT: obtaining N-(4-phenylaminophenyl)maleinimide.
