Reaction Steps
In place of 26.8 g of isophthalonitrile and 30 g of ammonia in Example 1, 24.6 g of terephthalonitrile, 52 g of dioxane and 25 g of ammonia were changed into the same autocLave and subjected to reaction in the same manner as in Example 1. It was found that the yield of 1,4-BAC was 88.2%, the yields of 4-methylbenzylamine and paraxylylenediamine were 7.2% and 2.1%, respectively, and that of other lower boiling and higher boiling products was 2.5%.
