    Abstract: METHOD FOR PRODUCING ALKYLARYL COMPOUNDS AND ALKYARYL SULPHONATES The invention relates to a method for producing alkyaryl compounds, by reacting a mixture with an aromatic hydrocarbon, in the presence of an alkylation catalyst to give alkylaromatic compounds and, optionally, by subsequent sulphonation and neutralization of the obtained alkylaryl compounds. Said method is characterized in that, on average, in said more than 0% and up to 100% of methyl branches are located in the longest carbon chain and less than 50% of the methyl branches are located at the 2-, 3- and 4-position, counting from the ends of the longest carbon chain.

    Abstract: Procedimiento para la preparación de compuestos de alquilarilo mediante reacción de una mezcla de monoolefinas de C10-14 con un hidrocarburo aromático en presencia de un catalizador de alquilación para la formación de compuestos alquilo-aromáticos y dado el caso sulfonación y neutralización subsiguientes de los compuestos de alquilarilo obtenidos, caracterizado porque en promedio en las monoolefinas de C10-14 están presentes más del 0 % y hasta el 100 % de las ramificaciones de metilo en la cadena de carbono más larga y menos del 10 % de las ramificaciones de metilo se encuentran presentes en las posiciones 2, 3 y 4, calculado desde los extremos de cadena de la cadena de carbono más larga, y las monoolefinas de C10-14 tienen en cada caso máximo una ramificación de metilo.

    Abstract: The present invention relates to a process for preparing optionally alkyl-substituted 1,4-butanediol by two-stage catalytic hydrogenation in the gas phase of C 4 -dicarboxylic acids and/or of derivatives thereof having the following steps: a) introducing a gas stream of a C 4 -dicarboxylic acid or of a derivative thereof at from 200 to 300° C. and from 10 to 100 bar into a first reactor or into a first reaction zone of a reactor and catalytically hydrogenating it in the gas phase to a product which contains mainly optionally alkyl-substituted gamma-butyrolactone; b) introducing the product stream obtained in this way into a second reactor or into a second reaction zone of a reactor at a temperature of from 140° C. to 260° C. and catalytically hydrogenating it in the gas phase to optionally alkyl-substituted 1,4-butanediol; steps a) and b) being carried out at the same pressure; c) removing the desired product from intermediates, by-products and any unconverted reactants; d) optionally recycling unconverted intermediates into one or both hydrogenation stages, said hydrogenation stages each using a catalyst which comprises =5% by weight, preferably from 5 to 95% by weight, in particular from 20 to 90% by weight, of an oxidic support, and the product mixture removed from the first hydrogenation stage being introduced without further purification into the second hydrogenation stage.
