An improved method for recovery of product alkanol and reactant olefin from a reaction mixture obtained via the sulfation and hydrolysis of C.sub.6 to C.sub.20 olefins, which comprise steps for a limited first evaporation of the reaction mixture under alkaline conditions to obtain an alkanol and olefin rich vapor and a liquid containing by-products of the sulfation and hydrolysis reactions, acid wash of the resulting liquid, and a second evaporation of alkanol and olefin from the washed liquid under acidic conditions. In addition to accomplishing separation of alkanol and olefin, the invention enhances selective utilization of C.sub.6 to C.sub.20 olefins for production of C.sub.6 to C.sub.20 alkanols.
