    Abstract: The preparation of alkylaryl compounds takes place by a) reaction of a C 4 /C 5 -olefin mixture over a metathesis catalyst to prepare a C 4-8 -olefin mixture comprising 2-pentene, and optional removal of the C 4-8 -olefin mixture, b) removal of from 5 to 100% of the 2-pentene present in stage a) and subsequent reaction over an isomerization catalyst to give a mixture of 2-pentene and 1-pentene which is returned to stage a), c) dimerization of the C 4-8 -olefin mixture obtained in stage b) following removal in the presence of a dimerization catalyst to give a mixture containing C 8-16 -olefins, removal of these C 8-16 -olefins and optional removal of a partial stream thereof, d) reaction of the c 8-16 -olefin mixtures obtained in stage c) or of the partial stream with an aromatic hydrocarbon in the presence of an alkylation catalyst to form alkyl aromatic compounds where, prior to the reaction, 0 to 60% by weight, based on the c 8-16 -olefin mixtures obtained in stage c), of linear olefins may additionally be added, e) optional sulfonation of the alkyl aromatic compounds obtained in stage d) and neutralization to give alkylarylsulfonates, where, prior to the sulfonation, 0 to 60% by weight, based on the alkyl aromatic compounds obtained in stage d), of linear alkylbenzenes may additionally be added if no admixing has taken place in stage d), f) optional mixing of the alkylarylsulfonates obtained in stage e) with 0 to 60% by weight, based on the alkylarylsulfonates obtained in stage e), of linear alkylarylsulfonate, if no admixing has taken place in stages d) and e).

    Abstract: The invention relates to a degreasing agent for treating skins, fur, limed skins and other intermediate products in leather and fur production, and for treating wool or related protein substances, based on non-ionic surfactants of the alcohol alcoxylate type. Alcohol alcoxylates are used which are obtained by reaction with at least one alcohol ROH with n mols of at least one alkylene oxide per mol of alcohol ROH, wherein R represents an alkyl radical containing between 5 and 30 carbon atoms, and having a main chain which contains between 4 and 29 carbon atoms and is branched in the centre thereof with at least one C1 - C10 alkyl radical; the alkylene oxide comprises between 2 and 6 carbon atoms; and n represents a whole number between 1 and 100. The invention also relates to a method for degreasing skins, fur, limed skins and other intermediate products in leather and fur production, and for treating wool or related protein substances, a degreasing agent according to the present invention being used. The invention further relates to the use of said degreasing agent.
