    Abstract: The invention relates to a shell catalyst containing ruthenium as an active metal, alone or together with at least one other metal of the auxiliary grou p IB, VIIB or VIII of the periodical system of the elements (CAS version), and applied to a carrier containing silicon dioxide as a carrier material. The invention also relates to a method for producing said shell catalyst, and to a method for hydrogenating an organic compound containing hydrogenable groups, preferably for hydrogenating a carbocyclic aromatic group to form the corresponding carbocyclic aliphatic groups or for hydrogenating aldehydes to form the corresponding alcohols, using the inventive shell catalyst. The invention further relates to the use of the inventive shell catalyst for hydrogenating an organic compound containing hydrogenable groups, preferably for hydrogenating a carbocyclic aromatic group to form the corresponding carbocyclic aliphatic groups or for hydrogenating aldehydes to form the corresponding alcohols.

    Abstract: Procedimiento para la purificación de cloruros de ácido carboxílico que se han fabricado mediante reacción de ácidos carboxílicos con fosgeno o cloruro de tionilo en presencia de un aducto del catalizador y se han separado de la fase que contiene el aducto del catalizador, caracterizado porque los cloruros de ácido carboxílico se tratan con un hidrohalogenuro de amidas del ácido carboxílico de fórmula general (I) en la que R1 representa hidrógeno o alquilo C1 a C3; R2 y R3 significan independientemente entre sí alquilo C1 a C4 o R2 y R3 juntos significan una cadena alquileno C4 o C5, en la que la solubilidad mutua del cloruro de ácido carboxílico y del hidrohalogenuro de la amida del ácido carboxílico (I) es baja y que el cloruro de ácido carboxílico así impurificado se aísla mediante la separación de la fase del hidrohalogenuro de la amida del ácido carboxílico.

    Abstract: Process for the purification of carbonyl chlorides which have been prepared by reacting carboxylic acids with phosgene or thionyl chloride in the presence of a catalyst adduct, in which the carbonyl chlorides are treated with a hydrohalide of carboxamides of the formula (I)in which R is hydrogen or C1- to C3-alkyl; R and R independently of one another are C1- to C4-alkyl, or R and R together are a C4- or C5-alkylene chain, and the carbonyl chloride purified in this way is isolated by separation off from the carboxamide hydrohalide phase.
