研究了膨润土改性后在环己醇脱水反应中的催化性能，考察了焙烧温度、反应温度、空速对催化活性的影响．实验结果表明：改性后的膨润土具有较好的酸催化活性 The catalytic performance of bentonite in the dehydration reaction of cyclohexanol was studied. The effects of calcination temperature, reaction temperature and space velocity on the catalytic activity were investigated. The experimental results show that the modified bentonite has better acid catalytic activity
