ABSTRACT:
A process for producing isopropyl alcohol by hydrating directly propylene and water in the presence of a strong acid solid catalyst which includes feeding continuously propylene, water which is the same as or more than propylene in terms of mole, and a saturated hydrocarbon (propane, butane and the like) to a reactor in which the above solid catalyst is filled or suspended, and carrying out a hydration reaction in the conditions of 50.degree. to 200.degree. C. and 60 to 250 atm while maintaining the concentration of isopropyl alcohol contained in the reaction liquid at 6 to 30 weight %, and then drawing a vapor phase out of the reactor, liquefying a part of thereof by reducing the pressure or cooling to separate vapor components, and refining crude isopropyl alcohol contained in the liquid phase to obtain refined isopropyl alcohol.
