在不同条件下制备了固体超强酸ＳＯ４２ － ／ＴｉＯ２ ， 用脉冲色谱法就其对环己醇脱水的催化活性进行了评价，并用正己烷作探针分子对其进行了差动热分析研究，发现沉淀温度、陈化时间、焙烧温度对其催化活性和酸强度有很大的影响
Solid superacid SO42 - / TiO2 was prepared under different conditions. The catalytic activity of SO42 - / TiO2 for dehydration of cyclohexanol was evaluated by pulse chromatography. Differential thermal analysis of n-hexane as probe molecule was carried out. Precipitation temperature, aging time, calcination temperature have a great influence on the catalytic activity and acid strength
