ABSTRACT:
In a single stage process for producing diisopropyl ether in the presence of an organic solvent, SO.sub.3 from a DIPE reactor effluent is transferred to an aqueous phase in a liquid extraction zone and removed from the aqueous phase using a basic ion exchange resin disposed in an SO.sub.3 removal zone. As a consequence, DIPE reactor effluent can be returned to the DIPE reactor to serve as a solvent and to assist in providing cooling to the DIPE reactor without causing catalyst deactivation.
