实验步骤: A flask was equipped as in Example 1. To a solution of maleic anhydride (1.8 parts) in 5.2 parts acetone was added a solution of 1 part hexamethylenediamine, 0.3 part triethylamine and 1.5 parts acetone over a 30-minute period. The resulting heterogeneous reaction mixture was maintained at 40°-50° C. for 30 minutes. Magnesium chloride hexahydrate (0.075 part) and 2.3 parts acetic anhydride were added all at once. The reaction mixture was maintained at 50° C. for 3 hours. Water (11 parts) was added to the cooled mixture and the precipitated product isolated by vacuum filtration. The filter cake was washed with water and dried in a vacuum oven. A 22% yield of N,N'-hexamethylenedimaleimide, m.p. 136°-139° C., was obtained.
