Abstract: A method for controlling the foaming of an aqueous organic compound-containing composition by the incorporation of a foam controlling amount of a compound of the formula: 1

Abstract: Water-soluble surfactant compositions comprising (A) 2,5,8,11-tetramethyl-6-dodecyne-5,8-diol and/or ethoxylate thereof and (B) a polyoxy(ethylene-propylene) block polymer and exhibiting a dynamic surface tension of up to 50 mN/m both at 1 Hz and 10 Hz in a 0.1 wt % aqueous solution thereof have such surface tension-reducing effects that when added to inks and paper coatings, they provide a surface tension comparable to those of fluorochemical and silicone surfactants. Because of a low dynamic surface tension, the surfactant compositions develop excellent substrate wetting, substrate penetrating and anti-foaming capabilities to comply with high-speed printing and coating, and overcome the environmental problem.

Abstract: The present invention provides storage water for storing a silicon wafer which is capable of decreasing attachment of fine particles including metals on a wafer surface, preventing a wafer surface from being etched by an alkaline component of a polishing agent, and preventing deterioration in wafer quality, especially in gate oxide integrity after cleaning, or preventing deterioration in haze and attachment of particles, and provides a method for storing a silicon wafer. The storage water for storing a silicon wafer comprises pure water and an organic acid having a chelating effect, which storage water is in the state ranging from being weakly acid to neutral, or comprises pure water and a nonionic surfactant.

Abstract: Methods and compositions effective for preventing or resolving emulsions of oil in aqueous solutions, preferably for preventing or resolving oil-in-water emulsions formed in aqueous brines used as completion fluids or workover fluids.

Abstract: A dispersant of formula 1 1

Abstract: Paint detackifiers and/or sedimentation agents are provided which contain amorphous alumina and/or alumina in pseudoboehmite or boehmite form having an average crystallite size of from 0.1 to 15 nm and/or the hydrates and hydroxyalkylpolysaccharides thereof.

Abstract: The invention is directed towards a chemical demulsifier formulation comprising an alkyl aromatic sulfonic acid additive and a process for demulsification and desalting crude oil using the demulsifier formulation.

Abstract: Belt pressing or other pressure dewatering of a high solids mineral suspension is facilitated by flocculating the suspension by mixing into the suspension anionic flocculant having IV at least 5 dl/g and a minor amount of a cationic flocculant which generally has IV at least 4 dl/g. The flocculants are normally such that counterionic precipitation occurs.

Abstract: Defoaming compositions comprising:

Abstract: A defoaming composition useful in high strength acid media includes an ester condensate of a C12-C20 fatty acid and a at least one alcohol derivative selected from the group consisting of C1-C4 alcohol ethoxylates having at least three ethoxylate residues per molecule, C1-C4 alcohol propoxylates having at least three propoxylate residues per molecule and C1-C4 alcohol mixed ethoxylate-propoxylates having at least three total ethoxylate and propoxylate residues per molecule. The condensate is preferably liquid at room temperature and miscible with water.

Abstract: Paraffinic oils which comprise in the range of from 45% to 100% basis mass per mass of one or more paraffinic hydrocarbon(s) and have an average molecular weight in the range of from 100-200 are useful as antifoam agents, especially in a surfactant-containing concentrate or an adjuvant concentrate for crop protection use.

Abstract: A polymer electrolyte which contains an inorganic pigment, having a sulfonated polystyrene resin as a principal ingredient, and is soluble to water.

Abstract: Bitumen emulsion including bituminous phase having one of pure bitumen, fluxed bitumen, and modified bitumen. The bitumen emulsion also includes an aqueous phase including water and an emulsifying agent. The bitumen emulsion further includes a breaking agent encapsulated in capsules allowing control of breaking of the bitumen emulsion, the control involving rupture of the capsules from a mechanical effect by a mechanical action produced on the bitumen emulsion. Processes of producing a bitumen emulsion. Processes of controlling breaking of a bituminous emulsion.

Abstract: A polymer electrolyte which contains an inorganic pigment, having a sulfonated polystyrene resin as a principal ingredient, and is soluble to water.

Abstract: This invention relates to improved bituminous emulsions, specifically to cationic medium-set and slow-set mixing grade emulsions. More particularly, it relates to emulsifying compositions which can be used to produce bituminous emulsions exhibiting high viscosity and low asphalt residues. The emulsifying compositions are combinations of fatty amine and/or polyamine, lignin, and nonionic surfactant. A preferred emulsifying composition can be produced by reacting the combinations of fatty amine and/or polyamine, lignin, and nonionic surfactant with formaldehyde.
