Studies on the catalytic synthesis of MTBE with H_3PW_(12)O_(40)/C

It is reported that the study on using H_3PW_(12)O_(40)/C as the catalyst to prepare MTBE from methanol and tert-butyl alcohol. And try to detailed to find out the factors influence the yields such as supported capacities of the catalyst, mol ratio of reactants,pressure, reaction temperature and time. Under the optimum condition, the highest conversion of tert-butyl alcohol is 77.2?% and the yield of MTBE is 56.4?%. The method has the advantages of simple operation, no corrosion to equipment, the catalyst which is heat-resisting and wear-resisting can be retrieved to reuse.
