Abstract: A catalyst carrier substance which can be obtained by reacting an inorganic particulate solid having surface hydroxyl groups with an organosilicon compound containing sulphur. The carrier may be converted to a supported catalyst by reaction with a compound or complex of platinum or rhodium. The catalysts can be recovered and recycled and are useful in hydrogenation, hydroformylation and oligomerisation reactions. They are of particular interest with respect to hydrosilylation reactions.

Abstract: Process for preparing an organosilicon product by the reaction of a silicon compound having ?SiH groups with an organic or organosilicon compound having aliphatic unsaturation in the molecule. The process is carried out in the presence of, as catalyst, a compound or complex of platinum or rhodium and also in the presence of a cobalt salt of a monocarboxylic acid. The cobalt salt improves the catalytic performance of the compound or complex of platinum or rhodium.

Abstract: Process for coating a surface with an organosiloxane composition to render it non-adherent. The organosiloxane composition is substantially solvent-free, has a viscosity not exceeding 4000 cS at 25 DEG C and comprises (1) a polydiorganosiloxane having silicon-bonded vinyl radicals (2) an organohydrogenpolysiloxane and (3) a catalyst which is RhX3(SR2)3 or Rh2(CO)4X2 in which X is halogen, preferably chlorine, and each R is alkyl, aryl, aralkyl, alkaryl or R'3SiQ wherein Q is a divalent aliphatic hydrocarbon radical and R' is alkyl, aryl, aralkyl or alkaryl or (CH3)3Si-. After application the composition is cured.
