In the production process of tributyl phosphate, the research of reaction kinetics of n -butyl chloride is a great significance to increase the yield of tributyl phosphate. Through kinetic study on the reaction of butyl chloride synthesis, the optimum production process conditions were determined. The effects of temperature and the initial concentration of hydrogen chloride and butanol on the synthesis were investigated. The reaction is a second-order reaction calculating with the differential method. The apparent kinetic equation is obtained where its apparent activation energy is 48.37 kJ/mol and its pre-exponential factor is 2 357.1 L/ （mol·min）. By comparison verification it could be found that the dynamic model values calculated were in good agreement with the experimental values, which could provide kinetic data to the preparation of tributyl phosphate.
