Vinyl - Uses and synthesis methods
production method
It is obtained by the reaction of acetylene and anhydrous hydrogen fluoride. After being purified by potassium dichromate, the acetylene dried by solid alkali and silica gel is mixed with anhydrous hydrogen fluoride, and poured into a reaction tube with aluminum fluoride catalyst to maintain the reaction at 250-350 ℃ (the reaction temperature increases with the decrease of catalyst activity). The gas flowing out of the reactor is cooled and washed with water to remove unreacted hydrogen fluoride, and then passed through the heated copper oxide catalyst layer to remove unreacted acetylene. At this time, in addition to fluoroethylene, the gas product also contains difluoroethane and trace amounts of acetylene, ethylene and non-condensable gases. Another method is to catalyze the addition of vinyl chloride and hydrogen fluoride to obtain 1, 1-fluorochloroethane, and then dehydrochlorinate to obtain fluoroethylene.
