Abstract: A purification process of crude oil soluble hydrocarbon sulfonic acid mixtures which comprises washing the crude oil soluble hydrocarbon sulfonic acid with water, contacting the washed, partially pure oil soluble hydrocarbon sulfonic acid with an excess of calcium carbonate to neutralize entrained sulfuric acid and adsorb impurities, removing the resulting calcium sulfate along with the remaining calcium carbonate, and recovering the pure sulfonic acid. Sulfonic acid produced in this manner is substantially free of impurities. The sulfonic acid is ideal for overbasing to high Total Base Number (TBN) sulfonate.

Abstract: A method for producing ammonium hydrocarbon sulfonate which comprises (1) contacting a sulfonation liquor comprising a hydrocarbon sulfonic acid, unreacted hydrocarbon, and SO.sub.3 with an alcoholic extraction medium in which the unreacted hydrocarbon is insoluble, (2) separating the insoluble hydrocarbon raffinate from the extraction medium, (3) removing a substantial portion of the extraction medium in a stripping tower to produce a hydrocarbon sulfonic acid having a residual amount of extraction medium, (4) neutralizing the hydrocarbon sulfonic acid with an excess of ammonia to produce an ammonia hydrocarbon sulfonate and heating the ammonium hydrocarbon sulfonate to remove residual volatile material. To conserve ammonia and solvent, this volatile material is returned to the stripping tower.

Abstract: A stable free sulfur containing mineral oil is produced in a two-step process. The first step of the process comprises producing a sulfurized solubilizing oil by reacting a lubricant oil with elemental sulfur until the uncombined sulfur content is less than about 0.5%. The second step comprising dissolving in the oil a quantity of sulfur such that the final concentration of uncombined sulfur is less than 2.0%.

Abstract: The product of the reaction of an amine, an olefin and sulfur trioxide, or sulfur trioxide complex, is an effective ashless antistatic agent for hydrocarbons. A small amount of the antistatic agent, when added to hydrocarbons, increases the conductivity of the hydrocarbon. The increased conductivity of the hydrocarbon conducts away any static charges that may be generated on the hydrocarbon and thus prevents the buildup of the static charges. The antistatic additive is represented by the general formula ##STR1## where R.sub.1 is a hydrocarbon group of less than 24 carbon atoms and R.sub.2 is hydrocarbon group with less than 18 carbons, or ammonia.
