Abstract: A surfactant for water/supercritical carbon dioxide microemulsions that can achieve high water dispersion ability, water/supercritical carbon dioxide microemulsion forming ability under a moderate condition, and high water solubilization rate and that reduces burden on the environment and ecosystem. Provided are a surfactant for stabilizing a water/supercritical carbon dioxide microemulsion including a compound of Formula (I) and a water/supercritical carbon dioxide microemulsion including the surfactant.

Abstract: Novel mixtures of long-chain (C10-C20) olefins are functionalized by conversion to aldehydes using an OXO process, or to sulfates, sulfonates, sulfones, sulfides, or sulfoxides by direct sulfonation. The aldehydes may then be hydrogenated to form alcohols, or aminated to form amines or amides. The olefins starting mixture may be acquired as a byproduct of the tetramerization of ethylene in the presence of certain chromium-containing tetramerization catalysts. The functionalized mixtures, and derivatives prepared therefrom such as alkoxylates prepared from the alcohols, may be useful as surfactants that may offer improved performance in many applications, while their preparation based on a byproduct mixture reduces their cost and also reduces waste-handling issues for this non-targeted stream.

Abstract: A method for upgrading heavy oils by contacting the heavy oil with a water-soluble aromatic polysulfonic acid salt and then thermally treating the contacted heavy oil. The polysulfonic acid salt can be recovered and recycled from contacting the heavy oil. The polysulfonic acid salt is recovered and recycled. The invention also relates to the upgraded product from the enhanced thermal treatment process.

Abstract: An emulsifier mixture comprising an emulsifier I of the formula in which X is O, S, CH2, NH or NR7, one or two of the radicals R1 to R6 are a group SO3?K? and the remainder of R1 to R6 are H or a C1-C18 alkyl group, R7 is a C1-C18 alkyl group and K is a countercation, an emulsifier II of the formula R8—O—(Z?O)n—SO3?K? in which the variables have the following meanings: R8: C1-C18 alkyl Z: CH2—CH2 or n: an integer from 1 to 50 K: a cation, and a nonionic emulsifier III.
Abstract: The present invention provides a dispersant and foaming agent combination that is useful in the production of gypsum wallboard and other aqueous cementitious products. The dispersant in the combination according to the invention is a naphthalene sulfonate-aldehyde condensate alkali salt polymer having a weight average molecular weight of from about 17,000 to about 47,000. The alkali is preferably an alkali metal and/or an alkaline earth metal. The aldehyde is preferably formaldehyde. The foaming agent used in the combination according to the invention is a soap, preferably an alkali salt of an alkyl ether sulfate and/or an alkyl sulfate. The combination of a high molecular weight dispersant and a foaming agent produces a gypsum wallboard core effect that more efficiently entrains air (i.e., creates void space), thereby lowering overall board weight without detrimentally affecting strength.

Abstract: Composition may be prepared in a single DEFI reactor comprising mixtures of (1) DEFI (directly esterified fatty acyl isethionate) and (2) a compound produced by the reaction of (a) isethionate with a fatty acid replacement (e.g., a multicarboxylic fatty acid, a fatty acid); or (b) fatty acid with an isethionate replacement (e.g., C2-C24 alcohols, C2-C20 organic acids, amines). Such mixtures are milder than DEFI alone while retaining substantially same foaming benefit.

Abstract: Aqueous surfactant compositions, with a high viscosity, comprising an anionic surfactant or a mixture of anionic surfactants, an alkyl ester of lactic acid or a mixture of alkyl esters of lactic acid and, optionally, an electrolyte. The above compositions can be used for the preparation of liquid detergents, either transparent or translucent, opaque or pearly, for use as "personal care" products, domestic detergents, car detergents.
Abstract: Salts of sulphonic acids of high molecular weight with alkyl groups derived from normal olefins, preferably normal C.sub.3 to C.sub.6 olefins and more preferably normal butene are used as emulsifiers in oil water systems particularly in oil in water emulsions such as microemulsions and white or milky emulsions.
