Abstract

PURPOSE:To obtain the titled compound useful as a raw material for polymeric compound, etc., on an industrial scale at a low cost, by reacting maleic anhydride with ammonia and reacting the reaction product, without separating from the system, with cyanuryl chloride in an essentially anhydrous polar aprotic solvent. CONSTITUTION:1mol. of maleic acid is made to react with 0.5-1.8mol., preferably 0.8-1.2mol., especially 1mol. or NH3 in a polar aprotic solvent (e.g., N,N- dimethylformamide) to obtain a compound of formula III. The objective maleimide is produced by reacting the reaction product with cyanuryl chloride without separating from the former reaction system. The process has various advantages such as high yield, easily available raw material, use of only one kind of solvent, high operation efficiency, low facility cost, recovery and reutilization of cyanuric acid, mild and rapid reaction, etc.
