Zusammenfassung:	PURPOSE:To produce a tertiary olefin, in high conversion and selectivity, keeping high catalytic activity even at a low temperature, by heating and dehydrating a tertiary alcohol in the presence of titanium oxide or zirconium oxide having SO4 group. CONSTITUTION:A tertiary olefin can be produced by the dehydration reaction of a tertiary alcohol (preferably a 4-10C alcohol) at 80-350 deg.C, preferably 100- 250 deg.C and atmospheric pressure - 10kg/cm pressure, in the presence of a catalyst consisting of titanium oxide or zirconium oxide having SO4 group. The catalyst can be produced by calcining a mixture of hydrated oxide of Ti or Zr and sulfuric acid or a mixture of hydrated oxide of Ti or Zr and their sulfate, at 400-700 deg.C. The content of SO4 group in the catalyst is 0.1-20wt%, especially 1-5wt%. The process is suitable for the production of isobutylene from tert- butyl alcohol.
