AbstractThe kinetics of the syntheses of N-alkyl, N,N-dialkyl, and N-(4-substituted phenyl) O-ethyl thioncarbamates from sodium ethyl xanthogenacetate, ten alkylamines, and eight substituted anilines were studied at 25, 30, 35, and 40 °C. The reactions were found to follow second-order kinetics. The kinetic (Arrhenius) parameters, such as the activation energy and the frequency factor, as well as the
摘要N-烷基,N,N-二烷基和N-(4-取代的苯基)O的合成动力学在25、30、35和40°C下研究了由黄原酸乙酯钠,十个烷基胺和八个取代的苯胺生成的亚乙基乙基氨基甲酸酯。发现反应遵循二级动力学。由二阶速率计算出动力学(Arrhenius)参数,例如活化能和频率因子,以及Eyring参数,例如标准熵,标准吉布斯能量和标准活化焓。常数。根据提出的动力学研究和使用MOPAC PM6半经验方法对反应机理进行了优化,推测了反应机理。 图形概要
