摘要:
The invention provides a process for alkylating an olefin with an isoparaffin comprising contacting an olefin-containing feed in the presence of a thermally stable composition comprising a non-swellable layered chalcogenide of an element having an atomic number of 4, 5, 12 to 15, 20 to 33, 38 to 51, 56 to 83 and greater than 90, inclusive, said layered metal chalcogenide comprising an interspathic polymeric chalcogenide of an element selected from Groups IB, IIB, IIIA, IIIB, IVA, IVB, VA, VB, VIA, VIIA, and VIIIA of the Periodic Table.
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.
