Title: THE REACTION BETWEEN SULFURIC ACID AND ALIPHATIC HYDROCARBONS. AMSCO 125- 82

Abstract

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)
