The Reaction Kinetics Study About The Pyrolysis Of1,1-Difluoro-1-chloroethane Yields Vinylidene Fluoride

This paper introduces the develop situation, mechanism, and categories of Vinylidene Fluoride.Pyrolysis of1,1-difluoro-1-chloroethane describe the main methods of producing Vinylidene Fluoride, especially for the method of preparing VDF from142b making a detail description. Based on the existing related literature research about the reaction mechanism, which is the pyrolysis of1,1-difluoro-1-chloroethane without dilution, established the reaction mechanism about the main product and the main byproduct in the pyrolysis of1,1-difluoro-1-chloroethane without dilution, builded the reaction system kinetic model.The factors that influenced the cracking reaction results under reaction temperature and reactant residence time were investigated using the experimental methods. The kinetic parameters equation of the pyrolysis of1,1-difluoro-1-chloroethane was parameter regressed by Matlab software, draw a conclusion about related major reaction rate constant.This paper also use the established kinetic model to calculate the industrial cracking reaction of1,1-difluoro-1-chloroethane. Computer simulation results show that the data by simulation calculation of the cracking reactor export main cracking product composition agree well with the actual value of industrial production, and also show that the kinetic equation which is obtained by experiment is correct and reliable. Finally, the kinetic equation applied to cracking reactor optimization and simulation calculation, which could be used for industrial reaction debugging and reference.
