A solid superacid catalyst, which was obtained by exposing Zr(OH)4 to 1N H2SO4 and then calcining in air at 500-750 deg C, was found to be highly active for the heterogeneous title reactions at 30-45 deg C.The reactions with the used catalyst gave identical results with those using freshly activated catalyst.
