    Abstract: The invention relates to a process for the preparation of alkylarylsulfonates by a) reaction of a C 4 -olefin mixture over a metathesis catalyst for the preparation of an olefin mixture comprising 2-pentene and/or 3-hexene, and optional removal of 2-pentene and/or 3-hexene, b) dimerization of the 2-pentene and/or 3-hexene obtained in stage a) over a dimerization catalyst to give a mixture containing C 10-12 -olefins, and optional removal of the C 10-12 -olefins, c) reaction of the C 10-12 -olefin mixtures obtained in stage b) with an aromatic hydrocarbon in the presence of an alkylating catalyst to form alkylaromatic compounds, where, prior to the reaction, additional linear olefins may be added, d) sulfonation of the alkylaromatic compounds obtained in stage c), and neutralization to give alkylarylsulfonates, where, prior to the sulfonation, linear alkylbenzenes may additionally be added, e) optional mixing of the alkylarylsulfonates obtained in stage d) with linear alkylarylsulfonates.

    Abstract: The invention relates to a method for the production of propene by multiple execution of the following sequence of steps, whereby in step 1 a mixture M1, essentially comprising unbranched C4- to C9 monoolefins (Components 04-9), 0 to 15 mol. % ethylene (component E), based on the components 04-9, 0 to 100 mol. % saturated hydrocarbons (components KG), based on the components 04-9, 0 to 30 mol. % olefins with more than 9 hydrocarbon atoms (components 0>9), based on components 04-9, 0 to 1 mol. %, based on the components 04-9, propene (component 03), 0 to 10 mol. %, based on the components 04-9, of other hydrocarbons (components KS), is brought into contact with a metathesis catalyst at a temperature of 20 to 350° C., with the proviso that the molar proportion of the sum of the 1-olefins and the sum of the 2-olefins to the sum of the components 04-9 and 0>9 is at least 0.5%, so long as the mixture M1 is not simultaneously or previously subjected to an isomerisation, correspondingly changing the proportion of 1- and 2-olefins, thus producing a mixture M2. In step II a mixture M1 is produced from a mixture M2 whereby a) propene and optionally components 0>9 and components KS are completely or partially removed and b) amounts of components 04-09 are added, a maximum of 1 mol. % of component E, based on the added amounts of components 04-09 and optionally other saturated or olefinically-unsaturated hydrocarbons, based on the added amounts of components 04-09, are added.

    Abstract: The present invention relates to a process for preparing polyol alkyl ethers by reacting compounds comprising at least three hydroxyl functionalities with olefins in the presence of acidic catalysts at temperatures of from 20 to 250° C. and pressures of from 0.5 to 10 bar, wherein the olefins correspond to the general formula (I) in which R1 is hydrogen and R2 is a linear or branched carbon radical having from 7 to 28 carbon atoms, or R1 and R2 are each linear or branched carbon radicals having from 1 to 27 carbon atoms, the sum of the carbon number of R1 and R2 being at most 28, to polyol alkyl ethers derived from compounds having at least three hydroxyl functionalities, not more than all but one hydroxyl functionality being replaced by a moiety of the general formula (VIII) to the use of these polyol alkyl ethers as surfactants and to laundry detergents and cleaning compositions comprising these polyol alkyl ethers.

    Abstract: A process for hydrogenating a monoolefinically unsaturated compound which bears at least two functional groups which are each independently selected from the group consisting of nitrile group, carboxylic acid group, carboxylic ester group, carboxamide group to a saturated compound which bears the same at least two functional groups, in the presence of a rhodium-containing compound, as a catalyst, which is homogeneous with respect to the reaction mixture.
