1.利用乙二胺与二胺基亚磷酸氢酯的四氯化碳溶液作用合成了二胺-N,N′-双(磷酸二烷基酯)(其中烷基为甲基,乙基,丙基,异一丙基,丁基) 2.以二丙基亚磷酸氢酯及二乙基亚磷酸氢酯依次作用于乙二胺的四氯化碳溶液合成了乙二胺-N-二乙基磷酸酯-N′-二丙基磷酸酯。 3.二烷基亚磷酸氢酯与乙二胺及四氯化碳的作用(在吡啶存在下)随着烷基的不同其反应初速度亦不同,其顺序如下: CH_3>C_2H_5>C_3H_7≥C_4H_9>i-C_3H_7 4.以二乙氧基磷酰氯与乙二胺作也顺利地合成了乙二胺-N,N′-双(磷酸二乙酯),这也是“1”法合成的乙二胺N,N′-双(磷酸二胺基酯)结构正确性的一个傍证
1. Diamine-N, N’-bis (dialkyl phosphate) (wherein alkyl is methyl, ethyl, Propyl, iso-propyl, butyl) 2. Dipropyl hydrogen phosphite and diethyl phosphite were sequentially reacted with ethylenediamine in carbon tetrachloride to synthesize ethylenediamine-N-bis Ethylphosphate-N’-dipropylphosphate. 3. Dialkyl hydrogen phosphite and ethylenediamine and carbon tetrachloride role (in the presence of pyridine) with the alkyl different reaction initial velocity is also different, the order is as follows: CH_3> C_2H_5> C_3H_7 ≥ C_4H_9 > i-C_3H_7 4. Ethylenediamine-N, N’-bis (diethyl phosphate) was also successfully synthesized by using diethoxyphosphoryl chloride and ethylenediamine, which was also synthesized by the method of “1” Amine N, N’-bis (phosphoric acid diamido ester) structure of the correctness of a Pian card
