Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a coating with catalytic action for synthesis of hydrogen cyanide on a molding. SOLUTION: In a method for manufacturing a coating with catalytic action, a molding is uniformly moistened with a coating dispersion liquid containing at least, one type of particulate platinum group element and any other coating component in a carrier liquid. In addition, the carrier liquid is evaporated and the coating is gradually heated at 1000-1350 deg.C in the presence of nitrogen and/or ammonium, so that the coating is shifted to a catalytic action effective state. In this case, a particulate nitride which has an average particle diameter considerably less than 100μm and contains elements such as aluminum, boron, titanium and silicon is used alone or in mixture form as another cationic coating component.

Abstract: Production of catalytically active coatings on the surface of ceramic mouldings comprises uniformly wetting the mouldings with a coating dispersion containing a particulate Pt metal and a further coating component in a carrier fluid, vaporising the carrier fluid, and converting the coating into the catalytically active state by slowing heating in the presence of nitrogen and/or ammonia to 1000-1350 degrees C. Particulate nitrides with Al, B, Ti or Si as cations are used as the further component. The particulate components have an average particle size of

Abstract: A method for the preparation of formaldehyde by dehydrogenating methanol at 650-1050 deg C in the absence of oxygen is carried out in the presence of a metal in gaseous form. Preferably sodium is used as the metal, vaporised separately from the methanol. An inert gas supplied to the reaction zone is used to dilute the reagents.
