Study on modified catalyst for vinyl chloride synthesis
The process was introduced of preparing 10%stannous chloride-10%copper chloride-[Bmim]BF4 ionic liquid catalyst using activated carbon modified with hydrochloric acid,nitric acid,and sodium hydroxide as carrier.The yield of synthesizing vinyl chloride from acetylene and hydrogen chlo-ride at different reaction temperature for different reaction time was discussed.The results showed that the stability and catalytic activity of the catalyst prepared by treating activated carbon with hydrochloric acid and nitric acid were improved,the catalytic activity of the catalyst prepared by treating activated carbon with sodium hydroxide was decreased.
