Abstract

N,N1-Ethylene-dimaleimide is prepared by adding a solution of maleic anhydride in benzene to one of 1,2-diamino-ethane in benzene, and heating the N,N1-ethylenedimaleimic acid formed with acetic acid and anhydrous sodium acetate. N,N1 - Hexamethylenedimaleimide and N,N1-o- or p-phenylenedimaleimide are prepared similarly.
