Abstract: Pyrroles are prepared by a process in which ammonia or an amine is reacted with a but-2-ene-1,4-diol in the presence of a supported catalyst containing copper, silver, zinc, palladium, nickel, cobalt and/or platinum and/or compounds of these metals as catalytic materials, and in the presence or absence of compounds of chromium and/or manganese as additional catalysts, in the gas phase. The pyrroles obtainable by the process of the invention are useful starting materials for the preparation of dyes, corrosion inhibitors, drugs and pesticides.

Abstract: Hydrogenation catalysts, which have a specific surface area of from 50 to 150 square meters per gram, solely or partially contain crystals having a spinel structure and copper in the form of copper oxide, and have been obtained by precipitating copper and aluminum in a ratio of from 0.25 to 3 atoms of copper per atom of aluminum from their compounds in the presence of a carbonate at a pH of from 4.5 to 9 and calcining the resulting precipitate at from 300 DEG to 800 DEG C., for the catalytic preparation of propanediols by hydrogenating hydroxypropionaldehydes at not more than 300 bar pressure and from 50 DEG to 200 DEG C., and processes for the preparation of propanediols by the use of such catalysts. The propanediols obtainable by the process of the invention, in particular 2,2-dimethylpropane-1,3-diol, are valuable starting materials for the preparation of lubricants, plastics, surface coatings and synthetic resins, for example corresponding polyesters.

Abstract: Catalysts for the preparation of carboxylates from an aldehyde and an alkanol in the presence of oxygen, which contain palladium and lead as active components, these being present on a carrier containing zinc oxide, and the palladium being applied as a palladium salt in a solution containing hydrochloric acid and then being liberated by reduction, and whose carrier consists solely of zinc oxide, are particularly active and selective.

Abstract: The invention relates to a process for the removal of the metal component of the catalyst from a polyphenylene ether solution produced in the preparation of high-molecular-weight polyphenylene ethers from monohydric phenols by oxidative coupling reaction with oxygen in the presence of a catalyst complex comprising a metal salt and an organic amine in the presence of a solvent and optionally an activator, by treatment with a precipitant which is a solid chemical reagent which is insoluble in the polyphenylene ether solution, and has been applied to an inert support substance which is adsorbent with respect to the precipitated substances. The precipitant is an organic P-, S-, O- or N-containing compound or an inorganic P or S compound which is soluble in water or aqueous acid solution, the support substance is a solid material of any desired shape with a specific surface area of from 50 to 1500 m /g and a porosity of between 50 and 75% which is insoluble in water, acid and organic solvents.
