Abstract: Suggested are alkoxylation products of 2-isopropyl-5-methyl-hexan-1-ol in which AO stands for an ethylene oxide, propylene oxide or butylenes oxide unit or their mixtures and n denominates an integer of from 1 to 100.

Abstract: The invention relates to a method for the dimerization of alcohols in the context of a Guerbet reaction, in which one or more alcohols (A) having 2 to 72 C atoms and 1 to 3 OH groups per molecule are reacted in the presence of (a) a base (B), (b) a carbonyl compound (C), and (c) a hydrogenation catalyst (H) from the group of metals ruthenium, rhodium, palladium, osmium, iridium, and platinum, said metals being in the elementary form, with the proviso that the alcohols (A) have at least one primary or secondary OH group, and that a C atom that carries at least one H atom as a substituent is directly adjacent to the C atom with said primary or secondary OH group.

Abstract: The invention relates to sulfosuccinates of the general formula (1), where M is hydrogen or a cation and the groups R4 and R5—independently of each other—are hydrogen or a cation or an alkyl group, wherein no more than one of the groups R4 or R5 is hydrogen or a cation, wherein said sulfosuccinates contain at least one alcohol building block that is assigned to the mono-alcohols with 8 to 36 carbon atoms in total, on the condition that said mono-alcohols are Guerbet alcohols (GA) containing at least two branches per molecule. Said sulfosuccinates are suitable as surfactants having improved dynamic surface tension.

Abstract: Polyurethanes, suitable as thickeners for aqueous systems, are obtained by reacting (i) one or more hydrophilic polyols containing at least two OH groups and at least two functional groups selected from ether and ester groups, having a molecular weight of at least 300 Daltons; (ii) one or more C8 to C36 Guerbet alcohols, which are produced from monoalcohols having 4 to 18 carbon atoms selected from the group of primary and/or secondary monoalcohols of formula (MA), where (a) the total number of carbon atoms in compounds (MA) is 4 to 18; (b) R1, R2 and R3 are independently hydrogen, or linear, branched or alicyclic, saturated or unsaturated alkyl; (c) optionally, R1 and R2, and/or R1 and R3, and/or R2 and R3 are linked together to form an alicyclic substructure; and (d) compounds (MA) have at least one branch; and (iii) one or more at least difunctional isocyanates.

Abstract: The present invention relates to nanoemulsions comprising alkyl and/or alkenyl ethers of alkyl and/or alkenyl (poly)glycosides, to a method for their preparation and also to their use. The present invention further relates to the alkyl and/or alkenyl ethers of alkyl and/or alkenyl (poly)glycosides themselves, and their use.

Abstract: The invention relates to an apparatus for producing hydrogen. Said apparatus comprises a reformer stage for converting hydrocarbon gas and water to hydrogen and other reformed products. At least one of the catalyst stages mounted downstream of the reformer stage is provided for the catalytic conversion of the reformed products. The apparatus also comprises a methanation stage which is mounted downstream of the catalyst stage and through which the medium flows in an axial direction. A flow guidance housing for a coolant extends in the axial direction of flow and is associated with said methanation stage. According to the invention, the flow guidance housing comprises at least two, preferably three or more cooling zones which have different cooling effects and which are disposed one after the other in the axial direction.
