    Abstract: Mezcla de tensioactivos que contiene (A) un componente de cadena corta que contiene el producto de alcoxilación de alcanoles, en el cual los alcanoles presentan 8 a 12 átomos de carbono y la cantidad media de grupos alcoxi por grupo alcanol en el producto de alcoxilación adopta un valor de 3 a 30, y los grupos alcoxi están seleccionados entre el grupo conformado por grupos etoxi, propoxi, butoxi y pentoxi y los alcanoles presentan un grado medio de ramificación de, al menos, 1 y (B) un componente de cadena larga que contiene el producto de alcoxilación de alcanoles, en el cual los alcanoles presentan 16 a 20 átomos de carbono y la cantidad media de grupos alcoxi por grupo alcanol en el producto de alcoxilación adopta un valor de 3 a 30, y los grupos alcoxi están seleccionados entre el grupo conformado por grupos etoxi, propoxi, butoxi y pentoxi y los alcanoles presentan un grado medio de ramificación de 0,0 a 0,3; o sus ésteres de fosfato o sulfato y carboxilatos de éter, asimismo, la relación del porcentaje en peso del componente de cadena corta (A) en la mezcla de tensioactivos, en relación al porcentaje en peso del componente de cadena larga (B) en la mezcla de tensioactivos, adopta un valor de 97 : 3 a 30 : 70.

    Abstract: The invention relates to the use of a 2-propyl-heptyl amine-based alkoxylate, which is alkoxylated with ethylene oxide, propylene oxide, butylene oxide, pentylene oxide, styrene oxide, cyclohexylene oxide, and/or decylene oxide, and to the quarternized derivative of said alkoxylate in cleaning agents, as an emulsifier, in the production of fibers, for treating leather, in printing inks, in formulations for construction chemistry or in formulations for flotation. The invention further relates to a mixture containing at least one of said alkoxylates and to at least one surface-active substance and to the use thereof.

    Abstract: The present invention relates to a process for separating at least one first material from a mixture comprising this at least one first material and at least one second material, which comprises the following steps: (A) contacting of the mixture comprising the at least one first material and at least one second material with at least one selective hydrophobicizing agent in the presence of a suspension medium so that an adduct is formed from the at least one hydrophobicizing agent and the at least one first material but not with the at least one second material, (B) contacting of the adduct from step (A) with at least one magnetic particle which is functionalized on the surface with at least one polymeric compound having a transition temperature LCST (lower critical solution temperature) at a temperature at which the polymeric compound has hydrophobic character so that the adduct from step (A) and the at least one functionalized magnetic particle agglomerate, (C) if appropriate addition of further suspension medium to the mixture obtained in step (B), (D) separation of the agglomerate present in the suspension from step (B) or (C) from the suspension by application of a magnetic field, (E) dissociation of the agglomerate separated off in step (D) by setting of a temperature at which the polymeric compound has hydrophilic character in order to obtain the at least one first material.
