Abstract: New ethylene-propylene copolymer oils containing 29-71 mol percent ethylene, the rest being at least substantially entirely propylene, said oils being of rich viscosity index, low pour point, and high stability, are produced from monoolefin mixtures containing ethylene and propylene employing specified vanadiumaluminum or titanium-aluminum Ziegler-type catalyst systems. Hydrogen under pressure is used with the vanadium-aluminum catalyst system to control molecular weight. Oils of lubricating oil viscosity can be produced directly, or after cracking higher molecular weight oil, said cracking usually, but not necessarily, followed by hydrogenating. Dewaxing can be employed to reduce pour point.

Abstract: The octane rating of gasoline alkylate may be improved by separating therefrom 2,4- and 2,5-dimethylhexanes (''''DMH'''') and subjecting said DMH to the following combination of steps: (1) oxidizing the DMH to form the corresponding hydroperoxides; (2) reacting of the hydroperoxides with propylene to yield the corresponding diols plus propylene oxide; and (3) dehydrating of the diols to produce 2,2,5,5-tetramethyltetrahydrofuran (''''TMTHF''''), which product is then added to the gasoline alkylate, thereby improving its octane rating. In addition, valuable propylene oxide is recovered as a by-product.
