摘要:
研究了氯代仲丁烷和二硫化钠溶液在相转移催化荆的作用下合成二仲丁基二硫醚的反应动力学,建立了动力学模型.该反应属于一级反应,其表观动力学方程:rA=-dcA/dt=47 098.67exp(-5 153.99/T)cA,表现活化能为42.85 kJ/mol,介于一般化学反应活化能40～200 k J/mol之间,属于化学反应控制过程,并对提出的动力学模型进行了实验验证,证实了该模型具有可靠性.
Abstract:
The reaction kinetics of sec-butyl disulfide synthesis by chlorinated secetane and sodium disulfide solution under the action of phase transfer catalyzed wattle was studied, and a kinetic model was established. The reaction belongs to the first-order reaction, and its apparent kinetic equation: rA=-dcA/dt=47 098.67exp(-5 153.99/T)cA, the performance activation energy is 42.85 kJ/mol, between the activation energy of the general chemical reaction 40~200 k J/mol, which belongs to the chemical reaction control process, and the proposed kinetic model is experimentally verified, which confirms the reliability of the model.
