Abstract: A method for the separation of methanol from MTBE contained in a reaction mixture comprising water, methanol, TBA and MTBE which comprises distilling the reaction mixture in the presence of added water in order to provide a distillate fraction containing most of the MTBE and a heavier distillation fraction containing most of the tertiary-butanol, water and methanol charged to the distillation column.
