【摘要】 对以新戊二醇、三氯氧磷和对苯二胺为原料，在三乙胺和４Ｎ，Ｎ二甲胺基吡啶（ＤＭＡＰ）催化作用下合成１，４二（５，５二甲基１，３二氧杂己内磷酰亚胺基）苯（ＮＢＰＡＮ）的反应进行了研究。讨论了ＤＭＡＰ对该反应的作用机制，合成收率达８２．７％。并用元素分析、ＩＲ和１ＨＮＭＲ表征了产物的结构。热重分析表明ＮＢＰＡＮ的起始分解温度为２８０℃，并在２８０～３１０℃迅速炭化，成炭率达３５．５８％。更多还原

【Abstract】 Bis(5,5 dimethyl 1,3 dioxacyclophosphorimide)benzene is synthesized by the intermedia of phosphorylation reaction of neopentyl alcohol and POCl 3,and p phenyldiamine in the presence of Et 3N and 4 N,N methylaminopyridine.The total synthetic yield is about 82.7%.The outstanding catalysis of DMAP is studied . The structure of NBPAN is confirmed by elementary analysis ,IR and 1 HNMR.The result of thermogravimetry shows that the beginning temperature of NBPAN decomposition is above 280℃,and rapidly carbonized between 280℃ and 310℃.The char yield is about 35.58% at 500℃.更多还原
