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.
A sulfonated petroleum composition which is substantially homogeneous under reaction conditions utilized to produce said composition, and comprising on a 100 organic weight percent total weight basis
A sulfonated petroleum composition which is substantially homogeneous under reaction conditions utilized to produce said compositions, and comprising on a 100 organic weight percent total weight basis
A sulfonated petroleum composition which is substantially homogeneous under reaction conditions utilized to produce said compositions, and comprising on an 100 organic weight percent total weight basis
A sulfonated petroleum composition which is substantially homogeneous under reaction conditions utilized to produce said composition, and comprising on a 100 organic weight percent total weight basis
A sulfonated petroleum composition as defined in claim 42 wherein said composition is subjected to a deoiling process comprising admixing said sulfonated petroleum composition with a hydrophilic solvent selected from the group consisting of water, a C.sub.1 -C.sub.5 alcohol and semipolar organic compounds so that a phase separation occurs and any unsulfonated oil is removed to attain a deoiled sulfonated petroleum composition.
