The conbination of MgCl2·6H2O with pyridine showed an ideal catalytic activity to give hexachlorocyclotriphosphazene in yield of 87% under the suitable conditions. The method is time saving.展开更多
合成了一种新的高分子模型化合物———六(4-乙氧羰苯氧基)三聚磷腈,用红外光谱、核磁共振氢谱、碳谱和质谱证实了该中间体的结构,用正交试验优化了该中间体的合成方法.结果表明,合成六(4-乙氧羰苯氧基)三聚磷腈的较好方法为:以2.4 g K2...合成了一种新的高分子模型化合物———六(4-乙氧羰苯氧基)三聚磷腈,用红外光谱、核磁共振氢谱、碳谱和质谱证实了该中间体的结构,用正交试验优化了该中间体的合成方法.结果表明,合成六(4-乙氧羰苯氧基)三聚磷腈的较好方法为:以2.4 g K2CO3为催化剂,用1 g六氯三聚磷腈与3.5 g对羟基苯甲酸乙酯在丙酮中回流8 h,产率为93.9%.展开更多
