Abstract
A process for the production of tertiary ethers from the reaction of isoolefins with lower alcohols, such as methanol, uses two distillation column reactors in series to maximize conversion, especially for isopentenes and isohexenes. The second distillation column reactor may be concurrently used as a C polishing reactor and a reactor for producing MTBE or ETBE from isobutene, for example.
