    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.
