of the reaction between O,O-diethyl ester of 1-amino-1-methyl-ethane phosphonic acid and phenylisocyanate, producing diethyl ester of 1-methyl-1-(N-phenylcarbamoyl-amino)ethane phosphonic acid is studied by IR spectroscopy. It is established that the reaction is of second order. The probable scheme of the reaction mechanism is suggested. The rate constant k of the initial stage of the reaction is determined
摘要 研究了1-氨基-1-甲基-乙烷膦酸的O,O-二乙酯与异氰酸苯酯反应生成1-甲基-1-(N-苯基氨基甲酰基-氨基)乙烷膦酸二乙酯的动力学。通过红外光谱。确定反应是二级反应。提出了反应机理的可能方案。确定反应初始阶段的速率常数 k。已确定速率常数在过程的高级阶段增加。观察到的增强归因于反应产物的自催化作用。
