    Abstract: Phosphabenzene compounds of the formula (I)where the radicals R1 to R13 are, independently of one another, hydrogen, COOM, SO3M, NR3X, NR2, OR, COOR or SR (where M=hydrogen, NH4 or alkali metal, X=anion, R=hydrogen or C1-C6-alkyl), or C1-C12-alkyl, C6-C12-aryl, C7-C12-aralkyl, C7-C12-alkaryl or C3-C6-heteroaromatics, where the alkyl, aryl, alkaryl and aralkyl radicals may bear the abovementioned radicals as substituents and two or more of the radicals may be joined to form aliphatic or fused-on rings, where at least one of the radicals R4 and R8 and at least one of the radicals R9 and R13 is not hydrogen, can be used for preparing hydroformylation catalysts.

    Abstract: The invention relates to methods for producing alkyl aryl sulphonates by a) reaction of a C4 olefin mixture on a methathetical catalyst to produce an olefin mixture containing 2 pentene and/or 3 hexene and optionally the separation of 2 pentene and/or 3 hexene, b) dimerisation of the 2 pentene and/or 3 hexene obtained in stage a) on a dimerisation catalyst to obtain a mixture containing C10-12 olefins and the optional separation of said C10-12 olefins, c) reaction of the C10-12 olefin mixtures obtained in stage b) with an aromatic hydrocarbon in the presence of an alkylation catalyst for forming alkyl aromatic compounds, whereby linear olefins can also be added prior to the reaction, d) sulphonation of the alkyl aromatic compound obtained in stage c) and neutralisation of the same to form alkyl aryl sulphonates, whereby linear alkyl benzoles can also be added prior to sulphonation, e) optional mixing of the alkyl aryl sulphonates obtained in stage d) with linear alkyl aryl sulphonates.

    Abstract: In a process for the hydroformylation of olefins having from 12 to 100 carbon atoms in the presence of a cobalt carbonyl catalyst at pressures of from 100 to 400 bar and at from 100 to 200° C., depressurization and recovery of the cobalt catalyst by extraction with an aqueous acid solution in the presence of atmospheric oxygen,(a) the extraction is carried out in the presence of a polymeric emulsion breaker selected from the group consisting of alkoxylated compounds containing amino, imino or OH groups, and(b) to achieve complete phase separation in the organic phase still containing small amounts of aqueous phase, the formation of relatively large droplets of the dispersed aqueous phase is effected in a coalescence stage.

    Abstract: In a process for producing n-butylalkyl ethers, (a) 1,3-butadiene or a butadiene-containing hydrocarbon mixture is reacted with an alcohol of formula ROH (I), in which the radical R is a C2-C20 alkyl or alkenyl group substituted or not with 1 to 2 C1-C10 alkoxy or hydroxy groups, a C6-C10 aryl or C7-C11 aralkyl group or a methyl group, at an increased temperature and pressure in the presence of a Brönsted acid or in the presence of a complex of an element of groups Ib, VIIb or VIIIb of the periodic table of elements with a phosphorus- or nitrogen-containing ligand, yielding a mixture of addition products of formulas (II) and (III); (b) the isomers are separated; (c) addition product III is isomerised into addition product II; (d) addition product II is hydrogenated in the presence of a homogeneous or heterogeneous transition metal element catalyst in the liquid phase or in the presence of a heterogeneous, transition metal element-containing catalyst in the gas phase, yielding n-butylalkyl ether of formula (IV).
