Abstract
Abstract A method of refining gasoline stock in order to obtain highoctane fuels which comprises mixing the gasoline stock with complex compounds of the lower-valency transition metals selected from the group consisting of lower-valency transition metal carbonyls, the complex compounds of slats of said metals with ntype ligands, and the complex compounds of salts of said metals with strong reducing agents, followed by heating the reaction mixture in the 80* to 100*C temperature range and distilling off the target product.
