330. CARRIER, E. W., AND NEIMAN, P. E. (Standard Oil Development Co.). [Dewatering Mixtures of Aqueous Alcohols.] French Patent 954,313: appl. filed Oct. 16, 1947, issued Dec. 22, 1949, in United States Mar. 15. 1947. Chem. Zentralb. 1950, II, p. 340.

Mixtures of aqueous alcohols, particularly of n-butyl, n-amyl- and n-propyl alcohols, are dewatered by fractional distillation. The alcohol mixture is allowed to settle in a decanter and the H₂O and alcohol phases are separated. By fractional distillation the 1^st phase yields almost pure H₂O and the 2d phase almost H₂O free alcohol mixture. The forerunnings of both distillations are combined and returned to the decanter. The alcohols are separated from the H₂O-free mixture by fractionation. Butylalcohol goes over at 117.7º and amykalcohol at 138º.
