This paper mainly studies that binary azeotrope system has been separated by the distillation-crystallization hybrid separa-tion process .Taken chlorobenzene and acetic acid for researching objects,the principle of hybrid separation process was studied and the experimental equipment was designed.By studing of the reflux ratio, final crystallization temperatures,the cooling rate and sweating, opti-mum conditions of separating chlorobenzene-acetic acid azeotrope by distillation-crystallization hybrid separation process were determined. The best reflux ratio was 2, the final crystallization temperature was -6℃, the cooling rate was 0.2618℃/min, sweating time was 2.5h.
