以膨润土为载体固载浓硫酸、浓磷酸，制备了两种固体酸，产物经IR表征，并用酸碱滴定法测定了酸的含量．将其用于催化环己酮与芳醛的羟醛缩合反应，分别得到5个相应的α，β-不饱和羰基化合物．结果表明，该反应条件简单，反应时间短（60～150 min），产率高（73．5％～88．2％），催化剂用量少（0．4 g），是合成该类化合物的有效途径．

Two kinds of solid acid were prepared by using bentonite as carrier to adsorb concentrated sulfuric acid and concentrated phosphoric acid , which were characterized by IR , and the amount of acids adsorb by bentonite were determined by acid-base titration.The cross-aldol condensation was carried out in the presence of the acidic bentonites and afford 5 corresponding α,β-unsaturated ketones .The results showed that this method provides an effective way to afford this kind of compounds , with several advantages such as simple work-up procedure , less amount of catalyst (0.4 g), high yield (73.5%~88.2%), shorter reaction time (60~150 min).
