摘　　要：研究了硫氢化钠和2-溴丙烷在催化剂作用下合成异丙硫醇的反应动力学,建立了动力学模型。硫氢化钠与2-溴丙烷反应属于一级反应,其化学反应动力学表征方程可表示为:rA=-dcA/dt=5.98334×1012exp(-11086/T)cA反应的表观活化能Ea=92.174kJ.mol-1,并对提出的动力学模型进行了实验验证,两者符合较好。Kinetics for synthesizing isopropyl mercaptan from Naris and 2-bromopropane in the presence of catalyst was studied ; the reaction and the kinetic model of the whole process were investigated. The kinetics equation is written as rA =- dcA/ dt = 5.983 34 × 10^12 exp（ - 11086/T） cA and the activation energy was determined to be 92. 174 kJ/mol in the Arrhenius equation. At last, the kinetic model was tested and verified by experiments, the result of which could satisfy the needs of the kinetic model.
