Abstract
A process for the treatment of ester-alcohol mixtures, which contain, together with the ester, the alcohol corresponding to the alcohol component of the ester, characterized in that hydrogen halide is added to the ester-alcohol mixture in a known manner, and The reaction is carried out at a temperature of not more than 100 [deg.] C. in filler bodies with a large surface area, any excess hydrochloric acid is removed from the lower end of the reactor and is continuously removed, in the form of steam, from the upper end of the reactor. The hydrochloric acid-free reaction mixture is separated in a subsequently coupled column, with the addition of water and in the presence of a cation exchanger, in an alkyl alcohol halide and in an aqueous alcohol-acid mixture, separated into a new one. The aqueous acid is added to the column and the remaining alcohol, which optionally contains an ester, is circulated in a closed loop. (Machine-translation by Google Translate, not legally binding)
