ABSTRACT OF THE DISCLOSURE A multi-purpose distillation column reactor is disclosed which may be used for the production of tertiary amyl methyl ether from the reaction of the isoamylenes contained in a light naphtha with methanol. Two reaction distillation zones are disposed above a stripping section. The stripping, in addition to removing the TAME product, also removes the C6 and heavier components. The first reaction distillation zone contains a hydrotreating catalyst for removing diolefins and mercaptans. The second distillation reaction zone contains an acid cation exchange resin for the etherification reaction and the entire column serves to fractionate the multiple component reaction system (reacts, inerts, products and contaminants) concurrently with the multiple reactions.
