Abstract: The invention relates to a method for extracting crude oil by means of CO2-flooding, in which a liquid or supercritical CO2 and at least one alk(en)yl polyglucoside is injected through at least one injection bore into an oil reservoir and crude oil is extracted from the oil reservoir by means of at least one production bore. The alk(en)yl polyglucoside is preferably dissolved in the CO2phase. The invention also relates to a method for extracting crude oil by means of CO2-flooding in which mixtures of alk(en)yl polyglucosides are used with alk(en)yl polyalkoxylates anionic surfactants.

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.

Abstract: The invention relates to preparations, in particular plant preparations which contain a mixture of at least two different active plant-protective substances, wherein a) at least one active substance is selected from a conazole group (active substance 1) and b) another active plant-protective substance (active substance 2) whose water solubility at a temperature of 20 0C is less than 20 g/l, c) at least one type of copolymer CP consisting of M monomers comprising a) at least one type of monoethylenically unsaturated monomer M1 comprising at least one sulphonic acid group and P) at least one type of neutral monoethylenically unsaturated monomer M2, wherein the quantitative ratio between the active substance 1 and the other active plant protective substance 2 ranges from 1:10 to 10:1. Said invention also relates to novel copolymers CP which are embodied in the form of polymers consisting of at least three types of different monoethylenically unsaturated monomers M and comprise, in the polymerisation incorporated form, a) at least one type of monoethylenically unsaturated monomer M1 comprising at least one sulphonic acid group, Pl) at least one type of neutral monoethylenically unsaturated monomer M2 whose water solubility at a temperature of 20 0C is less than 30 g/l and P2) at least one type of neutral monoethylenically unsaturated monomer M2b whose solubility at a temperature of 20 0C is greater than 50 g/l.

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.
