The selectivity of main product must be no less than 75 % . So the development of economic and practical technical process of triethylenediamine production is of great importance .

要求主产品 三 乙烯 二 胺选择性不小于75%，因此开发经济实用的生产 三 乙烯 二 胺的工艺具有重要意义。

Recently polyurethane foam develops quite rapidly which occupies approximately 80 % in the overall polyurethane products . With the application area becoming larger the demand for catalyst triethylenediamine increases drastically .

近年来聚氨酯泡沫塑料发展十分迅速，其产量 已在聚氨酯中占到80%，随着应用范围的日渐广泛，对催化剂 三 乙烯 二 胺的需求 亦会大幅度增加。
