Abstract: Compounds of the formulae: RO—X—NH2 (Ia); RO—X—NH3+Y− (Ib); RO—X—NH—Z—NH2 (IIa); and RO—X—NH—Z—NH3+Y− (IIb), 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 an aliphatic iso C13H27-group with average branching degree ranging from 1.5 to 3.5. The compounds are particularly suitable as flotation collectors for enriching an iron mineral from a silicate-containing iron ore.

Abstract: The present invention relates to a process for the preparation of hydrophobically associating macromonomers M and to the novel macromonomers produced by the inventive method. The macromonomers M comprise a copolymerizable, ethylenically unsaturated group and a polyether structure in block form which comprises a polyethylenoxy block and a hydrophobic polyalkylenoxy block consisting of alkylenoxy-units with at least 4 carbon atoms. Optionally, the macromonomers M may comprise a terminal polyethylenoxy block. The macromonomers produced by the inventive method are suitable for reaction with other monomers, in particular with acrylamide, to form a water-soluble, hydrophobically associating copolymer.

Abstract: La invención se refiere al uso de tioéteres (oxidados) de alcoxilatos de alcohol en detergentes y agentes de limpieza, especialmente en detergentes para lavar platos y a detergentes y agentes de limpieza, especialmente detergentes para lavar platos, que contienen tioéteres (oxidados) de alcoxilatos de alcohol. Dichos tioéteres (oxidados) son especialmente adecuados para usarse como surfactantes que tienen función auxiliar de enjuague (surfactantes auxiliares de enjuague). El término "oxidado" se refiere al átomo de azufre en el tioéter, el cual puede estar presente en forma oxidada como un sulfóxido (SO) o sulfonilo (SO2).

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.
