Dynamics Analysis on 1,1,1,2-Ttetrafluoroethane Synthesis through Trichloroethylene over Gas Phase Catalysts

Teleshike K F1 Barabanof V J2 (1.Russian Scientific Department Science Center,199034; 2.Russian Scientific Center Applied Chemistry,197198:St Petersburg, Russian Federation)  
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.
