Patent number: 9206348Abstract: A two-stage process for mineral oil production from mineral oil deposits with a deposit temperature of more than 70° C. and a salinity of 20 000 ppm to 350 000 ppm, in which an aqueous formulation comprising at least one glucan with a ?-1,3-glycosidically linked main chain, and side groups ?-1,6-glycosidically bonded thereto and having a weight-average molecular weight Mw of 1.5*106 to 25*106 g/mol, are injected into a mineral oil deposit through at least one injection borehole and crude oil is withdrawn from the deposit through at least one production borehole. The aqueous formulation is prepared in two stages, by first preparing an aqueous concentrate of the glucan, and diluting the concentrate on site with water to the use concentration.Type: GrantFiled: February 13, 2012Date of Patent: December 8, 2015Assignee: WINTERSHALL HOLDING GMBHInventors: Sebastian Briechle, Tillmann Faust, Stephan Freyer, Rajan Hollmann, Tobias Käppler, Bernd Leonhardt, Julia Kristiane Schmidt, Benjamin Wenzke, Foppe Visser

Patent number: 8574873Abstract: A process for the preparation of aqueous solutions of glucans having a ?-1,3-glycosidically-linked main chain and side groups having a ?-1,6-glycosidic bond by fermentation of fungal strains. The fungal strains secrete the glucans into the fermentation broth, in an aqueous culture medium, and the separation of the glucans from the fermentation broth is effected using asymmetrical filter membranes.Type: GrantFiled: December 14, 2010Date of Patent: November 5, 2013Assignee: Wintershall Holding GmbHInventors: Jörg Therre, Hartwig Voβ, Julia Kristiane Schmidt, Tillmann Faust, Rajan Hollmann

Publication number: 20070123717Abstract: A method for the production of C1-C10-alkyl 2-keto-L-gulonates by esterification of 2-keto-L-gulonic acid anhydrate with an anhydrous C1-C10-alkyl alcohol in the presence of an acidic homogeneous catalyst in a reactor cascade comprising at least two reactors, one of these reactors being a tubular reactor, without the water forming in the esterification being removed from the reaction space.Type: ApplicationFiled: December 10, 2004Publication date: May 31, 2007Applicant: Basf AktiengesellschaftInventors: Thomas Domschke, Martin Merger, Frank Haese, Peter Resch, Tillmann Faust

Patent number: 7091375Abstract: The invention relates to a method for producing 2-keto-L-gulonic acid-C4–C10 alkyl ester by esterifying 2-keto-L-gulonic acid (KGS) with an unsaturated, branched or unbranched C4–C10 alcohol. The inventive method is characterized by the fact that an aqueous KGS solution is reacted with a C4–C10 alcohol up to an esterification degree of 20 to 70 percent in a pre-esterification process carried out under acidic catalysis conditions; and the obtained product is dehydrogenated with an unsaturated, branched or unbranched C4–C10 alcohol in a continuous rectification device, whereby the esterification reaction continues, n-butanol preferably being used as the alkyl alcohol. In a preferred embodiment, the aqueous KGS solution is concentrated up to or beyond the limit of solubility prior to the esterification process, preferably by catalyzing a homogeneous or heterogeneous catalyst, especially sulfonic acid, at temperatures of 50 to 120° C.Type: GrantFiled: November 7, 2003Date of Patent: August 15, 2006Assignee: BASF AktiengesellschaftInventors: Thomas Domschke, Martin Merger, Georg Grossmann, Tillmann Faust
