Abstract A novel, convenient, one step synthetic procedure for the synthesis of mesoporous sulfated zirconia (m-SZ) using zirconium carbonate complex and its use as solid acid catalyst for the acetalization of different carbonyl compound is reported. The high specific BET surface area (234 m 2 g− 1) of m-SZ is achieved after the removal of the surfactant ( cetyltrymethylammonium bromide, CTAB) through calcination at 550 C for 6 h. ...
