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.
