Abstract: Mesotetraarylporphines are produced by reaction of pyrrole with an aromatic aldehyde in the presence of an organic substance having a dehydrogenating effect as an oxidizing agent and of a lower aliphatic carboxylic acid. The mesotetraarylporphines are suitable as such or in the form of their metal complexes particularly as photooxidation sensitizers.

Abstract: The present invention relates to a process for the preparation of phosphonomethylglycine in which N-phosphonomethyliminodiacetic acid N-oxide is brought into contact with a catalytically active quantity of at least one catalyst, selected from amongst a thionyl halide, ammonium dithionite or an alkali metal dithionite, a dialkyl sulfite, sulfur dichloride, sulfur dioxide and sulfurous acid, in a reaction chamber by metering the N-phosphonomethyliminodiacetic acid N-oxide into the reaction chamber in such a way that always at least 50% of the N-oxide metered into the reaction chamber are converted.

Abstract: The invention relates to a method for producing catalysts by immersion coating a metallic support with at least one platinum metal. An aqueous medium which comprises at least one platinum metal complex, at least one reduction agent and at least one complexer and which has a pH value of more than 4 is brought into contact with the metallic support in order to deposit the platinum metal, the platinum metal being deposited in the form of discreet, immobilised particles. The invention also relates to the catalysts obtained using this method and to their use for producing hydrogen peroxide and for hydrogenating organic compounds.

Abstract: PCT No. PCT/EP96/04504 Sec. 371 Date Apr. 21, 1998 Sec. 102(e) Date Apr. 21, 1998 PCT Filed Oct. 17, 1996 PCT Pub. No. WO97/15392 PCT Pub. Date May 1, 1997An improved process is provided for the recovery of catalyst components from oligomeric impurities which are formed during the industrial preparation of 2,5-dihydrofuran by the catalytic isomerization of vinyl oxirane followed by an essential separation of the oligomeric by-products which otherwise cause deactivation of the catalyst. The catalyst components consist essentially of (a) an onium iodide and (b) a Lewis acid selected from the group consisting of the chloride, bromide or iodide of the metals zinc, tin, cobalt and bismuth, preferably zinc, where the catalyst optionally includes a donor ligand. This separation is carried out by the steps of extracting the initial product mixture containing zinc, cobalt or bismuth halides as Lewis acids with hydrocarbons or chlorinated hydrocarbons containing from 5 to 14 carbon atoms in order to form two separate phases on standing, separating off the extraction solvent phase which contains the dissolved catalyst and then recovering the separated catalyst by distilling off the extraction solvent. The recovery of tin iodide requires the presence of a special onium halide component such as phosphazenium or phosphazanium halides, preferably the iodides, having a high molecular weight and especially those which contain from 16 to 72 carbon atoms while remaining soluble in the extracting agent.
