| 20110232489 | METHOD TO DECREASE DECOMPOSITION PRODUCTS IN SOLUTIONS THAT ABSORB ACIDIC GASES SUCH AS CARBON DIOXIDE AND THE LIKE IN THE PRESENCE OF OXYGEN - An amine solvent solution that is useful in absorbing acid gases from a liquid or gas feed stream may have an amine additive added thereto. Additionally or alternatively, the amine additive may be added to a liquid or gas feed stream. The addition of the amine additive decreases the presence of amine-derived contaminants and/or degradation of amine in the amine solvent solution. As such, the amine solvent solution is available for effective reuse in treating the liquid or gas feed stream and there may be a decrease in the corrosion within an amine treating system. | 09-29-2011 |
| 20110207873 | PREPARATION OF DI(AMINOACETONITRILE)S - A process for preparing a diaminoacetonitrile which includes reacting by contacting an amine comprising two primary amine groups with a cyanohydrin.

| 20110201829 | MODIFIED TRILOBE SHAPE FOR MALEIC ANHYDRIDE CATALYST - Embodiments of the present invention include improved shaped catalyst structures containing catalytic material comprised of mixed oxides of vanadium and phosphorus and using such shaped catalyst structures for the production of maleic anhydride. | 08-18-2011 |
| 20110166367 | REACTOR TEMPERATURE CONTROL USING PROBABILITY DISTRIBUTION - Embodiments of the present invention generally relate to temperature control of a reactor using probability distribution of temperature measurements. In one embodiment, a method of controlling a temperature of a chemical reaction includes injecting a reactant stream into a reactor and through a catalyst bed of the reactor. The reactant stream includes a hydrocarbon and oxygen. Injection of the reactant stream into the catalyst bed causes an exothermic chemical reaction. The method further includes circulating a coolant through the reactor, thereby removing heat from the catalyst bed. The method further includes measuring temperature at a plurality of locations in the catalyst bed. The method further includes calculating a fraction of the catalyst bed greater than a predetermined maximum temperature limit using a probability distribution generated using the temperature measurements. | 07-07-2011 |
| 20110124482 | SINTERING AIDS - Embodiments of the present invention disclosed herein include a sintering aid composition that has a material useful for sintering, an amine, and optionally a carboxylic acid. | 05-26-2011 |
| 20110118432 | NATURAL OIL BASED AUTOCATALYTIC POLYOLS - The present invention relates to a vegetable oil based autocatalytic polyol derived from the reaction product of an epoxidized vegetable oil and an alkanolamine. The autocatalytic polyol according to the present invention may be used as a replacement for all or a portion of petroleum derived polyols generally used in the production of polyurethane materials. The polyurethane materials produced may be used in a variety of applications, such as, foam, elastomer and coating applications. | 05-19-2011 |
| 20110112335 | PROCESS FOR THE PRODUCTION AND PURIFICATION OF PROPYLENE GLYCOL - The present invention relates to a process for producing an odorless and colorless industrial grade propylene glycol from glycerol obtained during the manufacturing of biodiesel. The process includes hydrogenating the glycerol to form a hydrogenated product, distilling the hydrogenated product to form a glycol product, and contacting the glycol product with a treatment bed. The propylene glycol may be used in various industrial and consumer applications and products such as personal care products. | 05-12-2011 |
| 20110009670 | CYCLOHEXANEDIMETHANAMINE BY DIRECT AMINATION OF CYCLOHEXANEDIMETHANOL - Embodiments of the present invention include methods for producing a cyclohexanedimethanamine by a reductive amination process. | 01-13-2011 |
| 20110009512 | REDUCTION OF ALDEHYDES IN AMINES - A tertiary amine, such as a tertiary amine catalyst that is useful in the production of polyurethanes, may undergo decomposition, which may result in the production of undesirable products. These tertiary amines, however, may be treated with a primary amine containing material to reduce the presence of the undesirable products to an acceptable level. Thus, a foam made from a treated tertiary amine will also have a reduction in the presence of the same undesirable products. | 01-13-2011 |
| 20100294499 | OIL RECOVERY EMPLOYING ALKYLENE CARBONATES - The present invention discloses an enhanced oil recovery method that contacts a gas and an alkylene carbonate with a subterranean formation. | 11-25-2010 |
