    摘要: Olefin undergoes conversion in the presence of water to a mixture of alcohol and ether which is then subjected to various downstream operations including distillation and decantation to provide an ether-rich product containing little if any water. If desired the ether can be combined in any predetermined ratio with co-produced alcohol to provide alcohol/ether mixtures of desired composition. The foregoing process is especially suitable to the conversion of propylene and propylene-containing streams to diisopropyl ether and mixtures of isopropyl alcohol and diisopropyl ether which are useful, inter alia, as octane improves for gasoline.
