    Abstract: Active Rhodium catalyst and impurities are separated from a hydroformylation process stream containing both active and inactive organo-rhodium catalyst by binding active catalyst and impurities to an acidic ion exchange resin containing an acidic group. The purified hydroformylation stream can be returned to the hydroformylation reactor. All or a portion of inactive rhodium can be reactivated before recycling purified hydroformylation process stream to the reactor. During regeneration of the resin, a neutral solvent is used first to remove impurities which are discarded, then an acidic solvent is used to remove active organic rhodium catalyst from the resin. Such active catalyst can be rehydrided and returned to the hydroformylation reactor. An ion exchange resin having at least one acid group disposed on a silica backbone and an active organo-rhodium complex from a hydroformylation process stream bound to the resin can be produced.

    Abstract: A substrate is provided with a resistant coating by the chemical-vapor deposition of hard material, by passing a gaseous mixture of a precursor of the material, an accelerant, an oxidant, and a carrier gas over the substrate surface, and then removing the by-products and unreacted materials; mixtures of hard materials are obtained by using a co-reagent in the gaseous mixture. The substrate is preferably heated. The figure shows a schematic of the apparatus which includes the precursor (102), the accelerant (104) which are vaporized and transferred to a reactor (120). A mixture of chromium oxide and tin oxide is the preferred coating material, obtained by decomposition of chromyl chloride and monobutyltintrichloride on the substrate surface in the presence of methylisobutylketone and air. Other metal mixtures can also be used.
