    Abstract: Wood preservatives for protecting wood or wood-base materials against animal pests, and which contain a perfluoroalkane sulfonate of the formula C nF2n+1-SO3 M where n is one of the integers from 1-14 and M denotes hydrogen or a cation, and a process for protecting wood or wood-base materials against animal pests with these compounds.

    Abstract: Methane-contg. gases are produced from 2-30C hydrocarbons, using Ni on a carrier as catalyst, by passing steam at pressures >1 atmos. and pre-heating to >250 degrees C to produce a temp. of 300-600 degrees C in the catalyst bed, in which the catalyst is simultaneously regenerated by wholly or partly replacing the hydrocarbon feed with methanol. Used for the mfr. of rich gases e.g. for use as natural gas substitutes. De-activation of the catalyst by carbonaceous deposits, as shown by a steady migration of the temp. profile through the bed, is reversed. Subsequent de-activation is not significantly faster e.g. half the original activity, as measured in bed thickness, can be maintained. Production of gas is not interrupted or permanently reduced.

    Abstract: Oxidation catalysts which in addition to oxygen ions, with or without NH4+ ions, contain molybdenum, tungsten, phosphorus and antimony as basic components, in the atomic ratio Mo:W:P:Sb=12:0.1-3:0.1-4:0.1-3, and which are prepared in a conventional manner by combining molybdenum, phosphorus, antimony and tungsten compounds in aqueous solutions or suspensions, removing the water and calcining the residues, the combination being carried out at chloride ion concentrations of less than 0.3 mole per mole of molybdenum and in the presence of ions of monocarboxylic acids of 1 or 2 carbon atoms, dicarboxylic acids or hydroxycarboxylic acids, are particularly suitable for the gas phase oxidation of methacrolein to methacrylic acid.
