Abstract: The use of a catalyst package which can be produced by the vapour deposition and/or sputtering of at least one substance active as a catalyst and/or promotor on fabrics, knitted materials or foils as substrates in a catalytic distillation process in which a heterogeneous-catalytic reaction is combined with simultaneous distillation or rectification on the catalyst package.

Abstract: Preparation of transparent yellow iron oxide pigments by precipitation of iron(II) hydroxide by addition of an inorganic base to an iron(II) salt solution and subsequent oxidation to FeOOH, in which a) an aqueous iron(II) salt solution having a molarity of at least 0.5 is first admixed at from 25 to 45@C in the presence of dissolved phosphates and, if desired, zinc salts with sufficient base for from 50 to 70% of the iron(II) ions used to be precipitated as hydroxide, then oxidising gas is passed through the mixture obtained until the pH has dropped to a value

Abstract: Acicular, magnetic iron oxide consisting of a core of gamma-iron(III) oxide and a ferrite shell containing a total of from 0.4 to 12% by weight of cobalt(II) ions and from 0.1 to 15% by weight of iron(II) ions, the percentages being based on the total amount of magnetic material, is prepared by a process in which an iron(II) hydroxide precipitate is applied to the gamma-iron(III) oxide core in a first stage and an iron-(II)/cobalt hydroxide precipitate is applied to the said core in a second stage, and the core is then converted to the ferrite shell by oxidation.
