【Abstract】 This study based on the fundamental research for the vapor-liq-uid data of DMF, benzene and alkane. The extractive distillation for purification ofthe imulity of trace alkane in coking benzene using DMF as a solvent was simulatedand got the optimization of operating conditions. The consultable in formation wereprovided for the industrialization experiment.更多还原
