Preparation and Catalytic Properties of Solid Base Catalysts — I. Metal Oxides

摘要: MgO, CaO, SrO and BaO are representative solid base catalysts that used for a number of base-catalyzed reactions. The surface basic strength is believed to follow the order: MgO < CaO BaO. Among these, has been studied most extensively, probably because samples definite structure with high area prepared much more easily by thermal pretreatment than structures SrO, similar thus, catalytic properties can be estimated from results obtained MgO. Although BeO RaO included in alkaline earth oxides, they have not toxicity radioactivity, respectively.
