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 a method for producing oil, in particular Winsor Type III microemulsion flooding, wherein an aqueous surfactant formulation comprising at least one non-ionic surfactant having 11 to 40 ethoxy unit and having a hydrophobic radical of 8 to 32 carbon atoms, and comprising at least one further surfactant different therefrom, is pressed through injection wells into an oil deposit, and crude oil is extracted from the deposit via production wells.

Abstract: Proceso para la extracción de petróleo, especialmente, la inundación con microemulsionesWinsor tipo III, en el que se inyecta una formulación acuosa de surfactante, que comprende por lo menos un alquilpolialcoxisulfato que contiene grupos propoxi, así como por lo menos otro surfactante diferente del primero, por pozos de inyección en un yacimiento de petróleo y se extrae el petróleo crudo del yacimiento por pozos de producción. El alquilpolialcoxisulfato que contiene grupos propoxi se obtiene aquí por sulfonación de un alcohol alcoxilado, cuyo alcohol alcoxilado se prepara por alcoxilación de un alcohol usando catalizadores de cianuro de metal doble o arcillas de hidróxido doble.
