In this paper,the heterogeneous azeotropic distillation was used to separate glycol and 1,2-propanediol with ethylbenzene,mixed xylene and cumene as azeotropic agent,respectively. Combining with the selectivity of azeotropic agent and the azeotropic point of azeotropic agent,suitable azeotropic agent was determined.
