Abstract
Kinetics for synthesizing di-sec butyl disulfide from 2-chlorobutane and sodium disulfide in the presence of phase transfer catalyst was studied in this experiment. And the reaction and the kinetics model of the whole process were established. It was proved to be a first order reaction and the chemical reaction kinetics characterization equation can be expressed as r A =- dc A / dt = 47 098. 67exp(- 5 153. 99 / T) c A. The activation energy was determined to be 42. 85 kJ / mol in the Arrhenius equation. And the reaction of synthesizing disec butyl disulfide belonged to control production of chemical reaction because the apparent activation energy was in range of 40 ~ 200 kJ / mol. And to our satisfaction,through experimental verification,the kinetic model was proved to be valid.
