Abstract: The present disclosure provides a scrubbing composition containing an aqueous solution of 2-(3-aminopropoxy)ethan-1-ol. The scrubbing composition is especially suited for use in removing acid gases, such as carbon dioxide and hydrogen sulfide, from gas streams.
Abstract: This invention concerns novel dispersants that are the reaction products of succinic anhydride-containing resins with certain amines. These water soluble dispersants have been found to be unique and highly effective dispersants for water insoluble agricultural suspension concentrate formulations.
Abstract: An agrochemical composition includes a homogeneous single-phase liquid crystal in thermodynamic equilibrium. The agrochemical composition can be a surfactant composition or a pesticide composition. The surfactant composition is a blend of surfactants, whereas a pesticide composition has an active ingredient and one or more surfactant adjuvants. A pesticide composition, or a surfactant composition in combination with an active ingredient, may be used to control pests.

Abstract: The present invention provides a process for producing a vanadium/phosphorus oxide catalyst by (i) preparing a catalyst precursor powder containing vanadium, phosphorus and an optional promoter element; (ii) converting the catalyst precursor powder into an activated catalyst by heat treatment; (iii) and compressing the activated catalyst into a desired shape to form the vanadium/phosphorus oxide catalyst. The vanadium/phosphorus oxide catalyst may be used in the production of maleic anhydride by the catalytic oxidation of hydrocarbon feed streams.
Abstract: A process for the separation of a first amine having a tertiary amine group and a secondary amine group such as N,N,N?-trimethylbis(aminoethyl)ether from a di-tertiary amine such as N,N,N?,N?-tetramethylbis(aminoethyl)ether, comprising: contacting a mixture of the first amine and the di-tertiary amine with a carbonyl compound capable of forming an enamine such that the carbonyl compound reacts with the first amine to form an enamine; separating the enamine from the di-tertiary amine; and subsequently converting the enamine to the first amine.

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: The present invention provides acylalkylisethionate esters useful in consumer products. The acylalkylisethionate esters are produced by reacting one or more carboxylic acids with one or more alkyl-substituted hydroxyalkyl sulfonates under esterification reaction conditions. The alkyl-substituted hydroxyalkyl sulfonates used as a raw material in producing the esters are prepared by reacting bisulfite with one or more alkylene oxides.

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.
