ABSTRACT:
A technique for sulfonating petroleum oil feed stocks which materially increases the extent of reaction between the sulfonatable components present in the feed stock and sulfur trioxide, and yields an improved sulfonated product. The invention provides a method which includes forming a liquid mixture of a petroleum oil feed stock and an organic additive, feeding such mixture to a reaction zone, and contacting the mixure with a reactable sulfur trioxide material. The additive appears to promote continuity of materials during the reaction in such a way that substantially homogeneous product compositions are obtained. The invention also includes the so-attained reaction products. Methods of neutralizing, digesting, purifying and other treatments to improve product utility are taught.
