Abstract: Processes for separating carbon monoxide from a hydrogen chloride-containing gas, which comprise reacting the carbon monoxide with chlorine to form phosgene and then optionally separating the phosgene from the hydrogen chloride-containing gas. The hydrogen chloride-containing gas that is used preferably derives from a phosgenation or isocyanate forming reaction.

Abstract: The present invention relates to a process for absorbing chlorine from a gas containing chlorine and carbon dioxide, in particular to a process for washing small amounts of chlorine out of a waste gas stream containing a large excess of carbon dioxide, wherein the washed waste gas can be released directly into the atmosphere.

Abstract: Processes are described which comprise: (a) reacting chlorine with carbon monoxide to form phosgene; (b) reacting the phosgene with at least one organic amine to form at least one isocyanate and hydrogen chloride; (c) separating the hydrogen chloride; (d) oxidizing the hydrogen chloride with oxygen in a gas phase to form additional chlorine; and (e) recycling at least a portion of the additional chlorine to the reaction of the chlorine and the carbon monoxide; wherein the oxidation of the hydrogen chloride is initiated via a high energy source which may be selected from electron-exciting radiation, ionizing radiation, a gas discharge, a plasma, and combinations thereof.

Abstract: The invention describes a process for the manufacture of a gas diffusion electrode involving preparing a powder mixture containing at least a catalyst and a binder, applying the powder mixture to an electrically conducting support, and pressing the powder mixture with the electrically conducting support.

Abstract: At least three-layered, coextruded, tubular, biaxially stretched seamless tubular casing comprising, viewed from the outside inwards, a) an outer layer A which comprises as the main component a polyamide or a mixture of several polyamides, b) optionally a layer B which has an oxygen-blocking character, c) optionally a core layer C which comprises as the main component a polyamide or a mixture of several polyamides, d) a layer D which has an adhesion-promoting action with respect to the adjacent layer C or B or A and the adjacent layer E and e) an inner layer E which comprises as the main component a polyamide or a mixture of several polyamides, f) optionally further layers and additives, wherein g) at least one layer comprises natural fibres having a fibre length in the range of from 5 to 10,000 ?m and/or a natural fibre mixture of various fibre types and/or fibre lengths. The use thereof as a foodstuffs casing is also described.
