Abstract: Provided herein are compositions useful as ink or coatings which contain novel dispersants that are capable of dispersing pigments which are traditionally difficult to disperse while maintaining acceptable levels of viscosity. Use of dispersants as taught herein enables the preparation of a wide variety of inks and coatings having high pigment loading and existing within a conventionally-useful viscosity range.
Abstract: Embodiments of the present invention disclose polymeric dispersants that are the reaction product of a polymeric acid and a hydrophilic amine.

Abstract: A surface active agent comprising an arylated methyl ester of a fatty acid, or mixture of fatty acids, derived from biodiesel or a triglyceride source is disclosed. The fatty acid mixture is condensed to methyl esters and alkylated with aromatic substituents under Friedel-Crafts conditions. The alkylated methyl esters may be alkoxylated using a catalyst derived from fatty acids, alkaline earth salts, and strong acids. The resulting nonionic surfactant may also be sulfonated to produce one class of anionic surfactants. The alkylated methyl esters may also be directly sulfonated to produce another class of anionic surfactants.

Abstract: 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.
Abstract: The present disclosure provides a surfactant composition for use in treating and recovering oil from an oil-bearing subterranean formation.

Abstract: The present disclosure relates to an amine catalyst composition for producing polyurethane foam. The amine catalyst composition includes an amine catalyst and a diluent containing a thickening agent and water. The use of such a diluent, in place of conventional glycols, reduces raw material and processing costs as well as environmental concerns during the production of polyurethane foam.

Abstract: 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.

Abstract: A process is described for producing crude maleic anhydride from a reactor effluent stream containing maleic anhydride. The reactor effluent stream is contacted with a solvent having a normal boiling point between about 250° C. and about 350° C., solubility of fumaric acid at least about 0.06 wt % at 60° C., solubility of maleic anhydride at least about 10 wt % at 60° C., solubility in water no higher than about 100 mg/L, density different from the density of water by at least about 0.020 g/mL, and water soluble hydrolysis products with molecular weight no higher than the molecular weight of pentanol. The solvent may be non-cyclic, non-aromatic, linear, and/or branched, and may have the general structure R1COOR2COOR3, wherein R1 and R3 are each linear or branched C3 to C5 groups and R2 is a linear or branched C3 to C8 group.

Abstract: In agricultural practice it is known to use emulsifiable oils (commonly referred to a Crop Oil Concentrates, COC) as bioefficacy enhancers for pesticides, especially herbicides. Cationic surfactants are widely known to be particularly effective bio-active enhancers for herbicides, especially for glyphosate-type herbicides. The present invention includes two novel aspects: 1) While the vast majority of COCs are petroleum-based paraffinic oils or esterified seed oils, this invention embodies a new oil phase, a hydrocarbon oil such exemplified by EXXON-MOBIL'S D-130, which when combined with the surfactants described herein, exhibits surprising enhancement of herbicidal activity in field tests; and 2) COC's are designed to form stable emulsions in water. The combination of cationic surfactants and phosphate esters in this invention not only form very stable emulsions in water, but, surprisingly, also form extremely stable emulsions in concentrated liquid fertilizers, including 32-0-0 fertilizer.
