Abstract: Preparation of triphenylphosphine (TPP) by reaction of triphenylphosphine dichloride (TPPCl2) with magnesium, aluminium and/or iron in the presence of an inert solvent by employing a TPPCl2 solution whose content of phosgene, chlorine, diphosgene, hydrogen chloride, thionyl chloride, sulphuryl chloride, phosphorus trichloride, phosphorus oxychloride and/or aliphatic halogen compounds ("active chlorine compounds") in total is below 1000 ppm of Cl.

Abstract: A process is described for the electrochemical cleavage of alkali metal sulphates into relatively highly concentrated solutions of alkali metal hydroxide and sulphuric acid by means of the use of a 3-compartment electrodialysis cell at temperatures of >/= 70 to equipped with an anion exchanger membrane, the polymeric ion exchanger matrix of which is composed of a styrene/divinylbenzene copolymer, having very highly basic quaternary ammonium groups, and a hydronium ion blocker, on the side of which facing the central chamber is located an anion exchanger layer or anion exchanger membrane having tertiary or secondary amino groups.

Abstract: The biological reactor is operated with microorganisms and/or enzymes for the oxidation of organic compounds which are employed in the presence of biocatalysts in the reactor chamber (4) (anode chamber), and the enzymes are regenerated on a polarised electrode (1), the polarisation of the electrode (1) taking place via a catalyst electrode (2) located in an electrolyte chamber (5) and separated from the reactor chamber (4) by a polyelectrolyte (3), where the electrode (1) is produced from an electrically conducting carbon material which is surface-oxidised at potentials epsilon h of +1.3 V to +10 V in aqueous oxygen-containing mineral acids.
