【Abstract】 A new process is proposed for separation of nitrochlorobenzene by using the azeotroepic vacuum rectification method.A suitable entrainer is determined,and the optimal technology parameters are determined through many experiments.The optimum conditions are as follows:the mass ratio of entrainer to material is 0.20∶1 and the reflux ratio 10.The results may be used for industrialized production.更多还原
