Abstract: The invention relates to a surfactant mixture containing, in relation to the hydrocarbon part (R1)(R2)-CH-CH2- at least three different ionic surfactants of general formula (I), wherein R1, R2, A0, k, X, o, Y, a, b, M have the meaning indicated in the description and the claims. The invention further relates to the use and production thereof and to aqueous surfactant formulations containing the mixtures and to a method for producing mineral oil by means of Winsor type III micro emulsion flooding, in which the aqueous surfactant formulation is forced through injection wells into a mineral oil deposit and the crude oil is removed from the deposit through production wells.

Abstract: A process for mineral oil production, especially Winsor type III microemulsion flooding, in which an aqueous surfactant formulation is used which comprises at least one alkyl polyalkoxysulphate containing propoxy groups, and also at least one further, different surfactant, is forced through injection wells into a mineral oil deposit, and crude oil is removed from the deposit through production wells. The alkyl polyalkoxysulphate containing propoxy groups here is prepared by sulphating an alkoxylated alcohol, the alkoxylated alcohol being prepared by alkoxylating an alcohol using double metal cyanide catalysts or double hydroxide clays.

Abstract: The present invention relates to water-soluble, hydrophobically associating copolymers, which are obtained in the presence of a non-polymerisable, surface-active compound and which contain novel hydrophobically associating monomers. The monomers comprise an ethylenically unsaturated group and a polyether block, the polyether block containing a hydrophilic polyethyleneoxy block and a hydrophobic polyalkyleneoxy block, which consists of alkyleneoxy units having at least 4 carbon atoms. The monomers can optionally have a terminal polyethyleneoxy block. The invention further relates to a method for producing the copolymers and to the use thereof.

Abstract: The present invention relates to a process for the preparation of hydrophobically associating macromonomers M and to the novel macromonomers produced by the inventive method. The macromonomers M comprise a copolymerizable, ethylenically unsaturated group and a polyether structure in block form which comprises a polyethylenoxy block and a hydrophobic polyalkylenoxy block consisting of alkylenoxy-units with at least 4 carbon atoms. Optionally, the macromonomers M may comprise a terminal polyethylenoxy block. The macromonomers produced by the inventive method are suitable for reaction with other monomers, in particular with acrylamide, to form a water-soluble, hydrophobically associating copolymer.

Abstract: COMPOSITIONS AND METHODS OF SYNTHESIS OF ANIONIC SURFACTANTS BY ALKOXYLATION OF A GUERBET ALCOHOL (GA) HAVING 12 TO 36 CARBON ATOMS USING BUTYLENE OXIDE, AND OPTIONALLY PROPYLENE OXIDE AND/OR ETHYLENE OXIDE FOLLOWED BY THE INCORPORATION OF A TERMINAL ANIONIC GROUP ARE DESCRIBED HEREIN. THE GA OF THE PRESENT INVENTION IS MADE BY A FACILE AND INEXPENSIVE METHOD THAT INVOLVES HIGH TEMPERATURE BASE CATALYZED DIMERIZATION OF ALCOHOLS WITH 6 TO 18 CARBON ATOMS. THE LARGE HYDROPHOBE ETHER SURFACTANTS OF THE PRESENT INVENTION FIND USES IN ENHANCED OIL RECOVERY (EOR) APPLICATIONS WHERE IT IS USED FOR SOLUBILIZATION AND MOBILIZATION OF OIL AND FOR ENVIRONMENTAL CLEANUP. FURTHER, THE HYDROPHOBE ALKOXYLATED GA WITHOUT ANIONIC TERMINAL GROUP CAN BE USED AS AN ULTRA- HIGH MOLECULAR WEIGHT NON-IONIC SURFACTANT.
