Abstract: A kind of Keggin structural 12-WP acid was prepared and used as catalyst to synthesize methyl tertbutyl ether (MTBE) from methanol and tertbutanol. The influences of the amount of 12-WP acid, the ratio of reactants and reaction temperature on the yield of MTBE were investigated. The results showed that the conversion of tertbutanol, selectivity of MTBE and the yield of MTBE could be up to 59.6%,74.5% and 44.4%, respectively when the amount of 12-WP acid was 2.16% of tertbutanol and the mole ratio of tertbutanol to methanol was 1∶1.2 at 100℃.-
