| 20080269351 | ALKYLATED HYDROXYAROMATIC COMPOUND SUBSTANTIALLY FREE OF ENDOCRINE DISRUPTIVE CHEMICALS AND METHOD OF MAKING THE SAME - An alkylated hydroxyaromatic compound prepared by reacting at least one hydroxyaromatic compound with a branched olefinic oligomer having from about 20 to about 80 carbon atoms in the presence of a acid catalyst. 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. | 10-30-2008 |
| 20090018359 | SYNTHETIC PETROLEUM SULFONATE - A synthetic petroleum sulfonate prepared by a process comprising (a) reacting at least one aromatic compound with a mixture of olefins selected from olefins having from about 8 to about 100 carbon atoms, in the presence of an acidic ionic liquid catalyst, wherein the resulting product comprises at least about 50 weight percent of a 1,2,4 tri-substituted aromatic compound or a 1,2,3 tri-substituted aromatic compound or mixtures thereof; (b) reacting the product of (a) with sulfur trioxide, which has been diluted with air; and (c) neutralizing the product of (b) with an alkali or alkaline earth metal hydroxide. | 01-15-2009 |
| 20090163669 | METHOD OF MAKING A SYNTHETIC ALKYLARYL SULFONATE - A process for preparing a synthetic petroleum sulfonate comprising (a) reacting a first amount of at least one aromatic compound with a first amount of a mixture of olefins having from about 8 to about 100 carbon atoms, in the presence of a strong acid catalyst, wherein the resulting product comprises at least about 60 weight percent of a 1,2,4-trialkylsubstituted aromatic compound; (b) sulfonating the product of (a); and (c) neutralizing the product of (b) with an alkali or alkaline earth metal hydroxide or ammonia. | 06-25-2009 |
| 20090170737 | 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 normal alpha olefin having from about 12 to about 30 carbon atoms per molecule that has been isomerized to obtain an isomerized alpha olefin having 15-98 wt % branching and a residual alpha olefin content of between from about 0.1 to about 30 wt %, thereby producing an alkylated hydroxyaromatic compound; (b) neutralizing the resulting alkylated hydroxyaromatic compound with an alkali metal base; (c) carbonating the alkali metal salt from step (b) with carbon dioxide; (d) acidifying the salt produced in step (c); and (e) overbasing the resulting alkylated hydroxyaromatic carboxylic acid. | 07-02-2009 |
| 20090186983 | METHOD OF MAKING A SYNTHETIC ALKYLARYL COMPOUND - A process for alkylating an aromatic compound comprising reacting (a) a first amount of at least one aromatic compound with a first amount of a mixture of olefins having from about 8 to about 100 carbon atoms, in the presence of a strong acid catalyst; and reacting the product of (a) with an additional amount of at least one aromatic compound and an additional amount of a strong acid catalyst, and optionally, with an additional amount of a mixture of olefins selected from olefins having from about 8 to about 100 carbon atoms, wherein the resulting product comprises at least about 80 weight percent of a 1,2,4 tri-alkylsubstituted aromatic compound. | 07-23-2009 |
| 20090209778 | METHOD OF MAKING A SYNTHETIC ALKYLARYL SULFONATE - A synthetic petroleum sulfonate prepared by a process comprising (a) reacting a first amount of at least one aromatic compound with a first amount of a mixture of olefins having from about 8 to about 100 carbon atoms, in the presence of a strong acid catalyst; (b) reacting the product of (a) with an additional amount of at least one aromatic compound and an additional amount of strong acid catalyst and, optionally, with an additional amount of a mixture of olefins selected from olefins having from about 8 to about 100 carbon atoms, in the presence of a strong acid catalyst, wherein the resulting product comprises at least about 80 weight percent of a 1,2,4-trialkylsubstituted aromatic compound; (c) sulfonating the product of (b); and (c) neutralizing the product of (b) with an alkali or alkaline earth, metal hydroxide or ammonia. | 08-20-2009 |
| 20100160703 | Method of making an alkylated aromatic using compound using an acidic ionic liquid catalyst - A process for alkylating an aromatic compound containing no hydroxyl groups comprising reacting at least one non-hydroxyl containing aromatic compound with at least one olefinic oligomer in the presence of an acidic ionic liquid catalyst, wherein the olefinic oligomer has a carbon range of from about C | 06-24-2010 |
