| Abstract: | A series of highly homogenous ZrO2-SiO2 mixed oxide were obtained via alcohol-aqueous heating method.The effects of the content of ZrO2 and calcination temperature on the acid properties of ZrO2-SiO2 mixed oxides,including acid amount and acidic type,were investigated.Catalytic performances of these materials were examined for the polymerization of tetrahydrofuran(THF).When ZrO2 content in mixed oxide was smaller than 30 mol%,the amount of total acidity of mixed oxides increased obviously as ZrO2 content in... |
