A solid superacid catalyst with an acid strength of H0 =/< -14.52 was obtained by impregnating Zr(OH)4 or amorphous ZrO2 with aqueous ammonium metatungstate followed by calcining in air at 800-850 deg C (13 wt.percent W); this catalyst was active for the isomerisations butane to isobutane at 50 deg C, and pentane to isopentane at 30 deg C.
