  • Process for producing tetrachloroethylene from tetrachloromethane using a molten salt catalyst
    Patent number: 4092370
    Abstract: Processes for producing tetrachloromethane and tetrachlorethylene are disclosed. Tetrachloromethane is produced by contacting a chlorinated feed material having two to four carbon atoms, and optionally including oxygen, hydrogen chloride or chlorine, with a molten salt catalyst of copper chloride together with an alkali metal or alkaline earth metal chloride at a temperature between 450.degree. and 750.degree. C. Tetrachloroethylene is produced by contacting tetrachloromethane, optionally together with chlorinatable material, oxygen and hydrogen chloride, with a similar catalyst at a temperature of 430.degree. to 650.degree. C.
