摘要：

Distillation-crystallization coupling process is a new kind of separation technology based on vapor-liquid equilibrium and solid-liquid equilibrium. The separation of azeotropic systems composed with Acetic acid and N-neptane by distillation-crystallization process (DCC) was studied in this paper. We apply the orthogonal experiment to search for the optimal technique process. The final results demonstrate that the DCC process can purify the heavy and light components over 90 wt% respectively, verifying the advantage of the DCC for the azeotropic systems separation.
