选用共沉淀法制备Mg-Al氧化物固体催化剂，并以此为基础制备异佛尔酮。比较了不同滴加方法和不同Mg/Al比例的催化剂性能。经研究认为当Mg/Al比例为1.0，采用反滴加的方法制备的催化剂反应活性高、选择性好且不易失活。

The research select co-precipitation methods to prepare solid base Mg-Al oxide catalyzer, and use the catalyzer to prepare isophorone. Compared the performance of catalyzer which prepared by dif-ferent methods of drop order and different ratios of Mg-Al. The result was when the ratio amount 1 and use back-titration route method to prepare isophorone had such merit: the catalyzer had higher activity, good se-lectivity and activity.
