  • Publication number: 20130109879
    Abstract: A process for converting naturally occurring fats and oils to sulfonated surfactants that can be used in a variety of applications where surfactants are found to be applicable including but not restricted to Enhanced Oil Recovery, paper and pulp processing, mining, metal treating, adhesives, coatings, pesticide formulations, herbicide formulations, fungicide formulations. The byproduct of such a process is a useful solvent or source of biodiesel fuel.

  • Publication number: 20120004431
    Abstract: 2-alkyl alkoxylated alcohol sulfonate surfactants having the structure R—O—(PO)x(EO)yCHR'CHR?CH2SO3Na are disclosed along with a process of making such surfactants. The surfactants are both electrolyte tolerant and tolerant to high temperatures and may be use for many applications where these properties are required.

  • Publication number: 20110120707
    Abstract: A process for the recovery of oil from subterranean reservoirs by injecting an aqueous fluid containing from about 0.05 to about 2.0% by weight of a surfactant of structure where m+n=1-30 or more, x+y=0-28, EO=oxirane, PO=methyl oxirane, M=H, Na, K, NH3, Amine, Ca, Mg, R and R1 are each separately and independently H, branched or linear alkyl, branched or linear alkenyl, A=aromatic, and, a+b=0 to 30.

  • Patent number: 7678937
    Abstract: The present invention discloses a process for producing light colored polyalkylated arylalkyl sulfonic acids. The polyalkylated arylalkyl sulfonic acids may be further neutralized with alkalis or amines to form the corresponding light colored sulfonated salts. The present invention also makes manufacture of polyalkylated arylalkyl sulfonic acids possible as first intent products using an inexpensive and simple reaction. The structure of the polyalkylated arylalkyl sulfonic acids produced using the process described in the present invention is shown below: Where R1, R2 and R3 are each separately and independently H, alkyl (branched or linear C1 to C30), R4?CH3(CH2)oCH(CH2)pCH3 m+n=4 to 28 o+p=3 to 27.

  • Publication number: 20080302531
    Abstract: This invention involves a process for recovering oil from a subterranean reservoir where an injection fluid containing one or more primary surfactants of the structure below along with one or more co-surfactants, solvent and optionally a viscosifier and one or more alkalis injected into one or more injection wells and the oil is recovered from one or more producing wells. where: Ar=any aromatic moiety, M=H, Na, K, Ca, Mg, NH4, or an amine, m+n=10 to 28, R, R?, R?=separately and independently H, CH3, branched alkyl having 2-30 carbons, linear alkyl having 2-30 carbons, CH3(CH2)mCH(CH2)nSO3M, O(CH2CH2O)xH, O(CHCH3CH2O)xH, or O(CH2CH2O)aO(CHCH3CH2O)bH, x=1 to 30, y=1 to 30, a+b=1 to 30. The primary surfactant may be prepared in the acid form at one location and shipped as a neat product to be formulated into the final injection brine at or near the point of injection.

  • Patent number: 6736211
    Abstract: A method of recovering oil or contaminants from subterranean reservoirs using a surfactant system where an adsorption reducing agent is injected before, after, and/or with the surfactant system. The adsorption reducing agent is formed by the reaction of an olefin sulfonic acid and phenol/aldehyde resin, the structure which is shown below where M may be Hydrogen or any cation, R is hydrogen, alkyl, alkenyl, etc., X is methylene or other aldehyde derived bridge, Y is hydrogen, ethylene oxide, propylene oxide, butylene oxide or mixtures of two or more of these, x+y is greater than 2 and n is equal or greater than 1.

  • Patent number: 6043391
    Abstract: New anionic surfactants and methods of preparation which are derived from aromatic or substituted aromatic molecules and alkenesulfonic acid. Wherein the aryl compound is alkylated and sulfonated in one-step with an alkene sulfonic acid prior to sulfonic acid neutralization. The methods allow the functional sulfonate group to be attached to the end of the alkyl chain rather than to the aromatic ring thus allowing for selective substituted groups, either branched, linear or alkoxylated or combinations thereof to be placed on the aryl compound prior to sulfonation and alkylation.
