ABSTRACT: "Process for the separation of methyl tert-butyl ether from reaction mixtures containing it". Methyl tert-butyl ether (MTBE) is prepared by the selective reaction of methanol with isobutylene contained in a hydrocarbon fraction with four carbon atoms (C4fraction, or C4hydrocarbons), operating in the liquid phase under the influence of acid catalysts. The reaction mixture containing MTBE together with me- thanol and C4 hydrocarbons is distilled, preferably at increased pressure, with separation of the methanol and the C4 hydrocarbons at the head and of MTBE at the bottom of the distillation column. This operation is carried out with an additional lateral liquid flow of a C4 hydrocarbon, or mixture of C4 hydrocarbons, to the column so as to maintain a methanol-C4 hydrocarbon com- position in the column at all times with a greater than azeotropic C4 -hydrocarbon content at the operating pressure. According to a preferred embodiment the distil- led C4-hydrocarbons, after separation from the metha- nol, are recycled as the lateral flow to the distillat- ion column. It is thus possible to separate MTBE com- pletely in a single distillation operation with a high purity as the product at the bottom of the column.
