Abstract :
The recovery of dimethylbenzene and butylacetate from industry spent solvent oil by two batch distillation was studied. The effect of separation temperature, time and reflux ratio on separation process was investigated. The experimental results showed that the concentrations of dimethylbenzene is 99.19% and butylacetate is 67% in top distillate product. The yield of dimethylbenzene is 86.14% and butylacetate is and 99.56%, respectively, under the appropriately conditions. The secondary results are better than that of the primary batch distillation.
