The catalysts and reaction conditions for the synthesis of methyl tert-butyl ether (MTBE) from methanol and tert-butyl alcohol were studied. It was found that Resin 732 had the highest catalytic activity when it was immersed in 1 mol/L HCl solution for 1 h. The factors influencing the yield of MTBE were discussed. Under the optimum reaction conditions, i.e. , the molar ratio of methanol to tert-butyl alcohol 1 : 1, amount of catalyst -24 wt. % (based on the system total mass), and time fpr boiling refluxing 7 h, the conversion of tert-butyl alcohol was above 51. 3% and the yield of MTBE reached 37. 2%.
