Concentrated sulfuric acid is regularly used to remove unsaturated hydrocarbon impurities from saturated aliphatic hydrocarbons. The reaction between concentrated sulfuric acid and saturated aliphatic hydrocarbons is not so well known. A survey of the chemical literature was found to include studies that show several relatively slow reactions. Isotopic exchange with D/sub 2/SO/ sub 4/, racemization of optically active alkanes, isomerization, cleavage to alkanes of lower molecular weight, combination to compounds of higher molecular weight and the formation of SO/sub 2/ were recognized. Amsco 125-82, the diluent used in solvent extraction, reacts with sulfuric acid forming sulfur dioxide and low boiling hydrocarbon fragments. The over-all reaction probably results in the formation of more stable hydrocarbons by rearrangement. The sulfuric acid treatment can thus produce a more desirable diluent. (auth
