    Abstract: The invention relates to a method for producing acetals by reacting allyl ethers with alcohols. According to said method, an allyl ether is reacted with an alcohol in liquid phase in the presence of a homogenous catalyst from an organometallic compound of an element from group VIA and/or VIIIA of the periodic table of elements or in the presence of a heterogeneous catalyst containing one or more elements from the groups IA, VIA, VIIA and/or VIIIA of the periodic table of elements in essentially water-free conditions.

    Abstract: The proposed process for producing n-butyraldehyde and/or n-butanol involves the following steps: (a) 1,3-butadiene is allowed to react with an amine of formula (I) R1R2NH, in which the groups independently of one another represent hydrogen, optionally substituted aliphatic or cyclo-aliphatic groups, or aryl or aralkyl groups, or are connected to a bridging unit which can contain heteroatoms, at high temperature and pressure and in the presence of a compound of a group VIIIb element, in the presence of an alkali metal amide, or in the presence of a basic metal oxide, to form a mixture of addition compounds of formula (II) and (III); (b) addition compound (III) is isomerised to addition compound (II); (c) addition compound (II) is isomerised in the presence of a homogeneous or heterogeneous transition metal catalyst in liquid phase or in the presence of a heterogeneous catalyst containing transition metal in the gas phase to produce enamine of formula (IV); and (d) the enamine (IV) is converted, by reaction with hydrogen and water, or water, in the presence of a homogeneous or heterogeneous transition metal catalyst in liquid phase, in the presence of a heterogenous catalyst containing transition metal in the gas phase, in the presence of an acid or in the presence of one of the above mentioned catalysts and of an acid, to n-butyraldehyde and/or n-butanol, the amine (I) being released and the released amine (I) being led back into sub-reaction (a).

    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 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.
