    摘要: A method for upgrading an aromatics-containing charge composition boiling in the gasoline boiling range comprises i) contacting the charge composition with a nitrating agent under nitrating conditions to form a product comprising nitrated aromatics; ii) hydrogenating a feed containing the product of i) under conditions sufficient to substantially reduce the nitro group of the nitrated aromatics so as to form a product comprising aromatic amines, water and heavy amines; and iii) removing the water and heavy amines from the product of step ii) to provide a gasoline boiling range product of an octane rating greater than the charge composition.

    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.
