【Abstract】 <Abstrcat> The auto-alternation between two relatively small accumulation drums was carried out via controlling temperature in the ceiling of the distillation tower. Taking isopropyl alcohol and n-propyl alcohol as experimental system, the principles of selecting optimal temperature were given, and the effect on separating high concentration system by this method was tested. The results showed that this operating method was more feasible, convenient and reliable.更多还原
