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 of emulsifying asphalt using a polyamine polybetaine, preferably a dibetaine, as an emulsifier or co-emulsifier and an emulsion of asphalt, water and a polybetaine, preferably a diamine dibetaine. The advantages of using a polyamine polybetaine as an emulsifier or co-emulsifier include its ability to provide superior cationic and anionic emulsions, and slow-setting emulsions at low use levels, and the excellent adhesion of the cured asphalt film.

Abstract: Disclosed are ethylenically unsaturated amine salts of sulfonic, phosphoric and carboxylic acids. The salts are surface active agents which are useful in a variety of applications as primary and/or secondary surfactants. The salts are especially useful as surfactants in emulsion polymerization reactions.

Abstract: A process for preparing a composition comprising a mixture with ester and amine function in the form of ester-amines, amines, salts of amines, monoglycerides and diglycerides all derived from monomeric, dimeric, trimeric, and/or tetrameric fatty acids contained in polymerized polyunsaturated oil comprising: (a) polymerizing a polyunsaturated vegetable or animal oil to form a polymerized oil, (b) treating the polymerized oil with water vapor, and (c) reacting the polymerized oil with an excess of at least one compound containing at least one hydroxyl function and at least one tertiary amine function, optionally in the presence of a catalyst. Said methods further comprise adding the compositions to an oil effluent as dispersing agents for hydrates.

Abstract: A dispersant is prepared from an amine and a hydrocarbyl-substituted acylating agent, wherein the hydrocarbyl substituent is a polymerized olefin having a polydispersity {overscore (M)}w/{overscore (M)}n of greater than 5. Such polyolefin substituents are prepared by polymerization of olefins in the presence of a calcined catalyst comprising a partially or fully neutralized ammonium salt of a heteropolyacid.
