ABSTRACT:
A method of decomposing organic halogen compounds including fluorinated hydrocarbons in the gaseous phase on superacid catalysts comprising titanium dioxide, with the formation of carbon doixide and hydrogen halides and particularly hydrolysis of perhalogenated methane derivatives on a sulfated titanium dioxide catalyst, and hydrolysis and oxidation of organic halogen compounds on a catalyst of sulfated copper oxide and sulfated titanium dioxide. The hydrogen halides liberated by the decomposition of the organic halogen compounds can be easily removed by conventional methods such as scrubbing with water.
