摘要
本文对精馏法和萃取精馏法进行萘与硫茚的分离进行了对比。探讨了用萃取精馏法从分步结晶萘残油中回收萘的可行性。提出了采用分步结晶—萃取精馏联合工艺的应用前景。
In this paper, a comparision was made between distillation and extractive distillation for separation of naphthalene and thionaphthene to produce refined naphthalene. The feasibility of recovery of naphthalene from the residue of fractional crystallization process by extractive distillation is discussed. The perspect of application of the combined fractional crystallization-extractive distillation.
