| 20090111717 | ENHANCED OIL RECOVERY SURFACTANT FORMULATION AND METHOD OF MAKING THE SAME - The present invention is directed to an enhanced oil recovery formulation which comprises:
| 04-30-2009 |
| 20090112014 | ISOMERIZED ALPHA OLEFIN SULFONATE AND METHOD OF MAKING THE SAME - The present invention is directed to an isomerized alpha olefin sulfonate and a method of making the same wherein the isomerized alpha olefin sulfonate is derived from sulfonating an isomerized alpha olefin with sulfur trioxide in the presence of air thereby producing an isomerized alpha olefin sulfonic acid, wherein the isomerized alpha olefin is derived from the isomerization of C | 04-30-2009 |
| 20090151941 | Method For Enhancing Oil Recovery With An Inproved Oil Recovery Surfactant - A method for enhancing oil recovery includes the step of providing a subsurface reservoir containing hydrocarbons therewithin. A wellbore is provided in fluid communication with the subsurface reservoir. A surfactant-polymer solution is formed for injection into the reservoir. The surfactant-polymer solution is formed by mixing a composition with at least one surfactant, at least one polymer, and at least one co-solvent or co-surfactant such that the surfactant-polymer solution is clear and aqueous stable. The surfactant-polymer solution is injected through the wellbore into the reservoir. A chaser solution is formed for injection into the reservoir. The chaser solution has an additional predetermined quantity of the co-solvent or co-surfactant. The chaser solution is injected through the injection wellbore into the reservoir to increase the production of hydrocarbons from the reservoir while maintaining the clear and aqueous stability of the surfactant-polymer solution. | 06-18-2009 |
| 20110003726 | LOW TEMPERATURE PERFORMANCE LUBRICATING OIL DETERGENTS AND METHOD OF MAKING THE SAME - The present invention is directed to a method for preparing an unsulfurized, carboxylate-containing additive for lubricating oils and the product produced by said method, wherein said method comprises a) neutralization of a mixture of at least two alkyl phenols using an alkaline earth base in the presence of a promoter, to produce a mixture of alkyl phenates, wherein the mixture of at least two alkyl phenols comprises at least a first alkyl phenol wherein the alkyl group is derived from an isomerized alpha olefin and a second alkyl phenol wherein the alkyl group is derived from a branched chain olefin; (b) carboxylation of the mixture of alkyl phenates obtained in step (a) using carbon dioxide under carboxylation conditions sufficient to convert at least 20 mole % of the starting alkyl phenols to alkyl salicylate; and (c) removal of at least about 10% of the starting mixture of at least two alkyl phenols from the product produced in step (b) to produce said additive. | 01-06-2011 |
| 20110046024 | ENHANCED OIL RECOVERY SURFACTANT COMPOSITION AND METHOD OF MAKING THE SAME - The present invention is directed to an enhanced oil recovery composition comprising (a) a surfactant comprising an alkylated hydroxyaromatic sulfonate having the general formula: | 02-24-2011 |
| 20110118154 | METHOD OF MAKING A SYNTHETIC ALKYLARYL SULFONATE - A process for preparing an alkylaryl sulfonate comprising (a) reacting at least one meta-xylene compound with olefin or a mixture of olefins having from about 10 to about 20 carbon atoms, in the presence of an acid catalyst, wherein the resulting product comprises no more than 40 weight percent of 1-alkyl-2,4 dimethylsubstituted aromatic compound and at least about 60 weight percent of 1-alkyl-3,5 dimethyl substituted aromatic compound; (b) sulfonating the product of (a); and (c) neutralizing the product of (b) with a source of alkali or alkaline earth metal or ammonia. | 05-19-2011 |
| 20110118160 | Alkylated hydroxyaromatic compound substantially free of endocrine disruptive chemicals - An alkylated hydroxyaromatic compound is disclosed which is prepared by reacting at least one hydroxyaromatic compound with at least one branched olefinic propylene oligomer having from about 20 to about 80 carbon atoms in the presence of an acid catalyst, wherein the at least one branched olefinic propylene oligomer is substantially free of any vinylidene content. The alkylated hydroxyaromatic compound has been determined to be substantially free of endocrine disruptive chemicals when the effects were quantified on pubertal development and thyroid function in the intact juvenile female rat. | 05-19-2011 |
| 20110130315 | LOW TEMPERATURE PERFORMANCE LUBRICATING OIL DETERGENTS AND METHOD OF MAKING THE SAME - A carboxylate detergent prepared by the process comprising (a) alkylating a hydroxyaromatic compound with at least one alpha olefin oligomer, derived from C | 06-02-2011 |
| 20110152571 | ISOMERIZED ALPHA OLEFIN SULFONATE AND METHOD OF MAKING THE SAME - The present invention is directed to an isomerized alpha olefin sulfonate and a method of making the same wherein the isomerized alpha olefin sulfonate is derived from sulfonating an isomerized alpha olefin with sulfur trioxide in the presence of air thereby producing an isomerized alpha olefin sulfonic acid, wherein the isomerized alpha olefin is derived from the isomerization of C | 06-23-2011 |
