The content of aliphaticdiamine was determined by thin-layer chromatography (TLC). The optimum synthetic art was studied and the equation of working curve was established.
采用薄层层析法测定脂肪族二胺的含量，探讨层析最佳工艺条件、制定工作曲线方程。

Nonisocyanate polyurethane(NIPU) was synthesized by aliphatic primary diamine and cyclocarbonate prepared from epoxy resin E-44.
以环氧树脂E-44为原料合成了环碳酸酯，再与脂肪族伯胺反应合成了非异氰酸酯聚氨酯。
