This catalyst has been proved to be a very effective from the viewpoint of activity,selectivity and reusability in the preparation of various important chemicals which have a number of difficulties with homogeneous catalysts, and can overcome such as corrosion,pollution,more vice-reactions, difficult of separation,and low selectivity. SO42-/ZrO2 is a kind of them,which has such advantages as high activity, hydrothermal stability, easy of separation of production with catalyst,non-corrosion and non-environment polluting.Magnetic matrix was prepared by chemical coprecipitation, then with solid acid oxide composite. The catalyst had high acid strength and magnetic. The activity of the...
