The presumption that new technology about distillation column with a single reactor can be used in photochlorination of acetic acid is first proposed in this paper. The fact that reaction distillation has obvious advantages in the number of theoretically perfect trays and energy consumption was obtained by theoretical analysis between the coupling of reaction and distillation and the independent operation, which lays a theoretical foundation on the application of the distillation column with a single reactor in photochlorination of acetic acid.
