Vinylidene fluoride is one of the most important monomers in fluorine industry,which is mainly prepared by the pyrolysis of 1-chloro-1,1-difluoroethane (HCFC-142b) at high temperature. This research progress in the pyrolysis mechanism of HCFC-142b to vinylidene fluoride was introduced. The technologies and the development trend of catalytic pyrolysis of HCFC-142b were reviewed together with the improvements in the structure of cracking tube. In addition,study on the rectification of vinylidene fluoride was discussed. It is proposed that in-depth study on the mechanism of the pyrolysis of HCFC-142b and the effects of the material and structure of cracking tube should be conducted. Learning from the research progress in the pyrolysis of hydrocarbons,the difficulty of high energy consumption,catalyst loss,coking and other problems faced in the pyrolysis of HCFC-142b will be solved.
