%X TEM, FTIR and XRD techniques are used to investigate the structure of HPWA-SBA-15. The results show that pores of HPWA-SBA-15 have regular two-dimensional hexagonal structure, and HPWA disperses well in the pore or pore wall of HPWA-SBA-15. NH3-TPD shows the HPWA-SBA-15 catalyst has acidic properties. ETBE is synthesized by the etherification reaction of alcohol and tert-butyl alcohol over several catalysts. Solid acid catalyst HPWA-SBA-15 is the appropriate catalyst which has the highest yield of ETBE than PW12/C and cation resin. The influences of reaction temperature, ratio of alcohol to tert-butyl alcohol are studied. At optimal operation condition, 30% HPWA on HPWA-SBA-15, reaction temperature 100℃, alcohol/tert-butyl alcohol molar ratio 2, the quality catalyst 0.9 g and raw material 10 g, the yield of ETBE is 59.55% and the selectivity is 90.2%.
