Abstract
Continuous prodn. of lower alcohols, esp. isopropanol, is effected by catalytic hydration of lower olefins, esp. propylene, in the presence of a strongly acidic opt. cross-linked cation exchange resin as catalyst esp. in a column contg. a fixed bed of the catalyst, through which the liquid or gaseous reactants flow downwards at 120-180 degrees C, 60-200 atm. and a column cross-sectional load of 1-40 esp. 5-25 moles water per cm2. at.hr., the molar ratio water : olefin being 1-30 : 1 esp. 10-20 : 1. The reaction temp. is increased gradually in such a manner that the catalyst efficiency (in moles alcohol per l. catalyst per hr.) lies always above a predefined minimum value within its useful life. Catalyst efficiency remains always above an economically acceptable value during the useful life of the catalyst. The alcohol concn. in the reaction pdt. remains approx. constant, thus facilitating recovery.
