Patent number: 6190646Abstract: A microemulsion is prepared containing: a mixture of (1) nitrogenous compounds, (2) from 10-5% by weight of an alkyl or alkenyl phosphoric ester surfactant, the alkyl and alkenyl groups of which contain less than 12 carbon atoms per group and the ester surfactant containing from 1 to 10 alkoxy radicals, (3) from 3 to 20% by weight of at least one cosurfactant, (4) a vegetable oil, an animal oil or a fatty acid and (5) a plasticizer. The microemulsion having a viscosity at 5° C. less than or equal to 200 mPa·sec and is stable at a temperature of −10° C. to +50° C. Further, the microemulsion is useful as a biodegradation accelerator.Type: GrantFiled: September 15, 1999Date of Patent: February 20, 2001Assignee: Elf AquitaineInventors: Jacques Tellier, Anne Basseres, Pascal Brochette, Alexandre Espert

Patent number: 4595512Abstract: The present invention relates to a process for preparing microemulsions between an acid phase and a hydrophobic phase in which a cationic surfactant and a cosurfactant are added to the reaction medium. This process makes it possible to obtain either a microemulsion of acid-in-oil type in equilibrium with an acid phase, or a microemulsion of oil-in-acid type in equilibrium with an organic phase, or a microemulsion in simultaneous equilibrium with the organic and acid phases.The process is applicable to numerous domains: controlled acidification, stimulatiion of oil-producing well formations, fracturing, liquid-liquid extraction of metal cations in hydrometallurgy, chemical reactions (sulfonation, sulfatation, protonic catalysis).Type: GrantFiled: September 19, 1983Date of Patent: June 17, 1986Assignee: Societe Nationale Elf AquitaineInventors: Jacques Tellier, Jean-Claude Gautier

Patent number: 4594151Abstract: Process of flotation of minerals, which consists of introducing the flotation collector into the mineral pulp to be treated in the form of a microemulsifiable composition. In general, the collector agents are organic compounds containing sulphur, particularly mercaptans, thioethers or polysulphides, which generally are very slightly soluble in water. This process is particularly suitable for minerals based on oxides and sulphides.Type: GrantFiled: May 2, 1985Date of Patent: June 10, 1986Assignee: Societe Nationale Elf Aquitaine (Production)Inventors: Raymond Delourme, Jean-Louis Detienne, Jacques Komornicki, Jacques Tellier
-
Patent number: 4587106Abstract: Liquid-liquid extraction of a substance from an aqueous solution thereof, which consists in preparing a microemulsion of this solution with a hydrophobic liquid in such a way that the layer of microemulsion is accompanied by a layer of consumed aqueous solution and a layer of hydrophobic liquid containing the substance to be extracted.Type: GrantFiled: December 23, 1982Date of Patent: May 6, 1986Assignee: Societe Nationale Elf AquitaineInventors: Denise Bauer, Jacques Komornicki, Jacques Tellier
-
Patent number: 4555343Abstract: Extraction of a metal compound from an aqueous solution by means of a hydrophobic liquid, with the production of a microemulsion; the aqueous solution has a pH of about 0.5 to 8; the surfactant employed for formation of the microemulsion is nonionic or anionic.Type: GrantFiled: February 24, 1983Date of Patent: November 26, 1985Assignee: Societe Nationale Elf AquitaineInventors: Denise Bauer, Jacques Komornicki, Jacques Tellier

Patent number: 4460692Abstract: There is disclosed a nutrient composition to be added to a hydrophobic medium for culturing microorganisms comprising a micro-emulsion of an aqueous solution of nutrient material in a liquid immiscible with water. As the source of nitrogen, compounds soluble in water are used, such as urea or ammonium nitrate, sulphate or phosphate, and, as the source of phosphorus, compounds soluble in water are used. The medium sould also contain a directly-assimilable source of carbon. Application of this composition for culturing of microorganisms allows operations to be carried out which comprise the degrading of hydrocabons covering an area of water or ground; an application of particular interest for operation is for combatting oil pollution of the sea by biological degradation. As the source of nitrogen, compounds soluble in water are used, such as urea or ammonium nitrate, sulphate or phosphate, and, as the source of phosphorus, compounds soluble in water are used.Type: GrantFiled: March 3, 1983Date of Patent: July 17, 1984Assignee: Societe Nationale Elf Aquitaine (Production)Inventors: Jacques Tellier, Andree Sirvins, Jean-Claude Gautier, Bernard Tramier
