Abstract
Olefins undergo conversion in the presence of water and recycled alcohol to a mixture of alcohol and ether which is then subjected to various downstream operations including distillation and extraction or decantation to provide an ether-rich product containing little if any alcohol or water. The foregoing process is especially suitable to the conversion of propylene and propylene-containing streams to diisopropyl ether which is useful, inter alia, as an octane improver for gasoline.
