    摘要： The vaporous reaction product from the continuous reaction of C.sub.3 -C.sub.4 monoalkanols with hydrogen chloride is removed, condensed, and split into a light organic phase and a heavy aqueous phase. The heavy aqueous phase is immediately distilled yielding HCl-containing reaction water at the bottom of the column and an alcohol stream at the head of the column from where it is returned to the synthesis. The light organic phase is washed with water, dried and, optionally, distilled. The water from this washing operation is neutralized, stripped off in order to remove dissolved organic constituents, and removed as waste water from the system.

    摘要： A process for the production of secondary butyl alcohol by the direct hydration of n-butenes in the presence of an acidic cation exchange resin catalyst which comprises depressurizing the vaporous product stream from a reactor to a pressure ranging from 15 to 40 bar and cooling the depressurizing product stream to a temperature of 120.degree. C. or below to liquefy the product stream, separating an aqueous fraction from said stream leaving an alcohol-butene/butane organic mixture, vaporizing said organic mixture, depressurizing said organic mixture to a pressure ranging from 3 to 30 bar and including a pressure of from 3 to 8 bar and introducing said depressurized organic mixture into a separation column to separate secondary butyl alcohol from said mixture.

    摘要： Practically anhydrous crude sec-butyl alcohol produced by catalytic direct hydration of n-butenes is freed by means of water from the azeotropically boiling and low-boiling by-products by continuous azeotropic distillation in a separation column, the prepurified anhydrous sec-butyl alcohol obtained is withdrawn and the high-boiling by-products are subsequently separated in a separate column.
