Abstract: The invention relates to a method for producing mineral oil by means of Winsor Type III microemulsion flooding, wherein an aqueous surfactant formulation which comprises, in relation to the alkyl part (R)(R)-CH-CH-, at least three different ionic surfactants of general formula (R)(R)-CH-CH-0-(D)-(B)-(A)-XY a/b M is pressed though injection wells into a mineral oil deposit and crude oil is extracted from the deposit via production wells. The invention also relates to surfactants formulations of ionic surfactants according to the general formula.

Abstract: The invention concerns a process for enriching an iron mineral from a silicate containing iron ore by inverse flotation comprising the addition of a collector or collector composition comprising at least one of the compounds of formulae RC(0)N(Z-0-X-NH2)2 (la); RC(0)N(Z-0-X-NH2)2H+ Y- (lb); in which X is an aliphatic alkylene group containing 2 to 6 carbon atoms; Z is an aliphatic alkylene group containing 2 to 6 carbon atoms; Y- is an anion; and R is a saturated or unsaturated, linear or branched, aliphatic or aromatic moiety having between 7 and 23 carbon atoms. The invention also relates to the novel compounds according to formulae (la) and (lb), compositions comprising said compounds and the use of compounds and formulations as collectors for enriching of iron mineral.

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 the use of (oxidized) thioethers of alcohol alkoxylates in detergents and cleaning agents, especially in dishwashing detergents, and to detergents and cleaning agents, especially dishwashing detergents, containing (oxidized) thioethers of alcohol alkoxylates. Said (oxidized) thioethers are especially suitable for use as surfactants having rinse aid function (rinse aid surfactants). The term "oxidized" refers to the sulfur atom in the thioether, which may be present in oxidized form as a sulfoxide (SO) or sulfonyl (SO2).
