摘要
研究了以三氯乙烯为主要原料,在铬镁氟化催化剂存在下,用氟化氢气相氟化制备1,1,1,2-四氟乙烷的反应机理,建立了动力学模型。并以此为依据确定了按双反应釜方案试验装置的工艺流程,当氟化氢和三氯乙烯的质量流量分别为60.86kg/h和97.54kg/h时,1,1,1,2-四氟乙烷的产量可达96.48kg/h。
Reaction mechanism for 11,1,2-tetrafluoroethane preparation is carried out through gas phase fluorination by hydrogen fluoride over chromium-magnesium fluorination catalysts with trichloroethylene as main materials and dynamics models are set up. According to the conditions above, a flow process is set up to test the equipment with two autoclaves. Output of 11,1,2- tetrafluoroethane reaches 96.48 kg/h when mass flow of hydrogen fluoride and trichloroethylene is at 60.86 kg/h and 97.54 kg/h.
