硫钠盐与气态氯甲烷在加压釜内以水作溶剂反应可制备甲胺磷。其反应式为: 反应系统的压力靠氯甲烷气体的压力维持。为研究甲胺磷收率(％)与反应温度(℃)。反应压力(公斤/厘米~2)和反应时间之间的定量关系,本文将概率论与数理统计回归分析的方法应用到该项试验中,建立了相应的回归方程,并进行了预报。实验结果表明,计算值与实测值能获得较好的吻合。 Methamidophos can be prepared by reacting sulfur and sodium salts with gaseous methyl chloride in water in an autoclave. The reaction is: The pressure of the reaction system is maintained by the pressure of the methane gas. To study methamidophos yield (%) and reaction temperature (° C). The relationship between reaction pressure (kg / cm ~ 2) and reaction time, this paper applies the method of probability theory and mathematical statistics regression analysis to this experiment, establishes the corresponding regression equation, and forecasts it. The experimental results show that the calculated value and the measured value can get a good match.
