ABSTRACT:
A process for converting propylene to isopropyl alcohol by contacting water with a propylene-containing feed at a mole ratio of water to propylene of at least about 0.5:1 (water:olefin), usually about 1:1-10:1 in the vapor and/or liquid phase under propylene hydration conditions. The hydration is carried out in the presence of a relatively constrained intermediate pore size zeolite such as ZSM-35 or ferrierite as the hydration catalyst. The zeolite is used in the acid form and with a crystal size of not more than 0.2.mu. to give high activity for conversion to isopropyl alcohol.
