一种增强型β晶型聚烯烃成核剂N,N'-二环己基对苯二胺的合成

Synthesis of A Reinforced β-Crystalline Polyolefin Nucleating Agent N,N'-bis-cyclohexanyl-p-phenylen

采用环己胺与对苯二甲酰氯为原料合成了β晶型聚烯烃增强型成核剂N,N＇-二环己基对苯二酰胺.实验确定的最佳合成反应条件为：环己胺和对苯二甲酰氯摩尔比为1.95 ～2.0;反应时间为5～6h;反应温度为（82±2）℃.

Experiments using cyclohexane amine with terephthaloyl chloride for the synthesis of N, N＇ - bis-cyclohexanyl-p-phenylendicarbonylamine, a ncleating agent used for manufacture of reinforced β - crystalline polyolefin, was synthesized by use cyclohexyl amine and terephthalyl chloride （TPC） as raw materials. The optimum reaction conditions are ： the molar ratio of cyclohexylamine and TPC is 1.95 to 2. 0 ; the reaction time is 5 - 6 h ; the reaction temperature is （ 82 ± 2） ℃.
