The catalytic hydrolysis of dichlorodifluoromethane (CFC-12) was investigated over solid acid Ti(SO₄)₂. The catalytic activity decreased with the calcination temperature. When space velocity was 6 l h^-1 g-cat^-1, the CFC-12 conversion at 310℃ over Ti(SO₄)₂ calcined at 350℃ remained about 98.5% during 360 h on stream, and the selectivity to by-products remained zero. The findings enlarged the scope of traditional catalyst systems for the CFCs decomposition.
