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.
