An experiment on distillation of E.H. P.-mT. C. P. system was performed by use of pot still in a range of residual air pressure from 1.0×10-3mmHg to 3.5×10-1mmHg.The effects of residual air pressure and liquid surface temperature on relative volatility have become clear. The agitation effect on relative volatility was also investigated.
