摘　　要：主要利用Aspen plus软件对HFC-152a-HF体系的VLE(气液平衡)数据进行回归与热力学检验,得到HFC-152a与HF的Wils-HF方程交互作用参数。对稳定工况下的乙炔法制备HFC-152a反应系统进行了模拟,得到了该工况下装置的工艺参数,所得结果为工业生产提供了相应的依据。Vapor- liquid equilibria（ VLE） data for anhydrous hydrogen fluoride（ HF） and 1,1- difluoroethane（ HFC- 152a） were determined via data regression using Aspen plus in this study,and the thermodynamic data were also investigated. A modified interaction parameters of the Wils- HF model between HFC- 152 a and HF were obtained in the present study. Under the stable conditions,synthesis of HFC- 152 a from ethyne and anhydrous hydrogen fluoride had been systematic simulated and the process parameters was obtained. The obtained process parameters provided the corresponding theoretical basis for industrial production.
