Abstract：

The　new　nanosolid　superacid　SO42-/CoFe2O4　is　prepared　by　using　nanometer　chemical　technology.　The　structure　of　catalysis　has　been　studied　by　XRD,　TEM,　IR,　XPS　and　BET　methods.　The　results　show　that　SO42-/CoFe2O4　is　superfine　solid(<　50nm)　belong　to　nanocrystal　and　has　high　specific　surface　area　(157　m2　·　g-1).　SO42-　is　combined　with　metal　ions　of　catalysis　in　a　bidentate　state.　The　catalytic　activity　and　strength　of　acid　(Ho　<-　14.5)　is　measured　by　the　model　reaction　of　the　synthesis　of　ethyl　acetate.
