摘要

The process condition of dephenolization of bisphenol A-phenol adduct is studied, by using the solid decomposition reaction on the basis of thermodynamic property of bisphenol A-phenol and the kinetics of solid decomposition reaction. Two processes of vacuum dephenolization and nitrogen fluidized dephenolization were experienced. The results show that the proposed processes of dephenolization is feasible. A new method of dephenolization in production of bisphenol A is developed.
