| Abstract: | The applications of heteropoly acids(salts),either supported or unsupported,as catalysts for condensation reactions were reviewed.phosphotungstic acids(salts),silicon tungsten acids (salt),phosphorus and molybdenum heteropoly acids(salts),and also SiO_2,activated carbon,zeolite, and other supported heteropoly acids(salts) in the condensation reactions were discussed.Compared with the traditional acids,heteropoly compounds as catalysts possess the advantages of high catalytic activity,high selectivity and no pollution.Heteropoly acid catalysts are effective in promoting the condensation reactions.Problems encountered in the application of heteropoly compounds for condensation reactions were analyzed. |
