Abstract
Metal-containing, shaped, polymeric, tertiary and/or secondary organosiloxane amine compounds are introduced which contain the metals Pd, Pt, Ru, Rh individually or in combination as well as optional promotors and/or moderators. The organosiloxane amine functioning as carrier for the metals contains the units ##STR1## and/or units ##STR2## in which R.sup.1 to R.sup.5 are a group ##STR3## with R.sup.6 as a double-bonded group bound to N and Si (e.g. an alkylene group) and X is an amine group such as The carrier substance can be cross-linked with cross-linking agents containing Si, Ti, Zr or Al. The metal-containing product is spherical in form and is defined by the parameters of sphere diameter, specific surface and pore volume as well as bulk density. A method of production is disclosed which can be carried out in several variants as well as the use of the metal-containing product as catalyst for hydrogenation reactions and oxidation reactions.
