Abstract: The invention relates to a method for producing a polyamide by converting a mixture containing a monomer that comprises a nitrile group and at least one additional functional group that is capable of forming a carboxamide group, in addition to water in the presence of titanium dioxide, which acts as the catalyst. Said method is characterised in that the titanium dioxide has a BE T surface area ranging between 5 and 35 m2/g, determined by means of a volumetric process according to a multipoint method, as per the German standard DIN 66 131.

Abstract: A process is described for preparing tetrahydrogeranylacetone in which pseudoionone, geranylacetone and/or dihydrogeranylacetone in a liquid phase, in which particles of a catalyst which is capable of preferentially hydrogenating carbon-carbon double bonds over carbon-oxygen double bonds are suspended, is conducted through a device which inhibits the transport of the catalyst particles in the presence of a hydrogen-containing gas.
