The precursors of S₂O₂^-8/Fe₂O₃-SiO₂ solid acids prepared via co-precipitation method were modified by microwave hydrothermal treatment.After being impregnated in a (NH₄)₂S₂O₈ solution and calcined at a certain temperature,solid acid catalysts were formed.The samples were characterized by XRD,TEM,N₂ gas adsorption/desorption and chemical analysis.The catalytic activities of the solid acids were evaluated by esterification of acetic acid and butanol.In addition,the solid acid catalysts were compared with other catalysts prepared under normal conditions.The results show that adding SiO₂ retards the formation and growth of Fe₂O₃ crystals.After the precursors were modified via 250 W microwave hydrothermal treatment,the solid acids had a moderate specific area (37.1 m²/g) and a narrow pore size distribution,and the sulphur content was 6.02%.The solid acid showed a high catalytic activity.At 3 h reaction time,the convertion of acetic acid reached 97.7%.
