    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: Desengrasante para el tratamiento de pieles, pieles de pelo, pieles en tripa y demás productos intermedios en la producción de cuero y pieles, así como de lana o tejidos proteínicos derivados, basado en tensioactivos no iónicos del tipo de los alcoxilatos de alcohol, caracterizado porque se emplean alcoxilatos de alcohol, que se obtienen por reacción de al menos un alcohol ROH con n moles de al menos un óxido alquileno por mol de alcohol ROH, en el que - R es un resto alquilo con de 5 a 30 átomos de carbono, que presenta una cadena principal, que es la cadena alquílica más larga del resto R, con de 4 a 29 átomos de carbono, que está ramificada en el centro de la cadena con al menos un resto alquilo C1 a C10, empezando con el átomo de carbono C 2, partiendo la numeración desde el átomo de carbono (C 1), que está unido directamente al átomo de oxígeno contiguo al resto R y terminando con el átomo de carbono ù-2, siendo ù el último átomo de carbono de la cadena principal,
