Definitions

  • the present invention relates to gas odorization.
  • City and coke oven gases obtained by thermal processes contained intense smelling components and therefore had a strong inherent smell, so that escaping Gas could be perceived easily.
  • the acrylic acid esters A include acrylic acid methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, pentyl, hexyl, heptyl, octyl and dodecyl esters.
  • mixtures of acrylic acid-C 1 -C 6 -alkyl esters are used as component A; a particularly preferred combination contains methyl and ethyl acrylates side by side.
  • the acrylate mixtures can each contain the lower and the higher esters in a weight ratio of 9: 1 to 1: 9, preferably 7: 3 to 3: 7.
  • Preferred compounds (I) are e.g. 2-methylpyrazine, 2,3-dimethylpyrazine, 2,6-dimethylpyrazine, 2,3,5-trimethylpyrazine, tetramethylpyrazine, 2-ethylpyrazine, 2,3-diethylpyrazine, 5,2-methylethylpyrazine, 2,3-methylethylpyrazine, 5,2,3-methyldiethylpyrazine and 3,5,2- and 3,6,2-dimethylethylpyrazine, 2,3-methylethylpyrazine and tetramethylpyrazine are preferred.
  • the nitrogen compounds B can be used in amounts of 1 to 100, preferably 30 to 100, in particular 10 to 50 parts by weight per 1,000 parts by weight of A are used become.
  • the odorants can be used to protect against unwanted oxidation antioxidants included, as for example in Römpp-Lexikon Chemie Version 1.3 are described.
  • the antioxidants C are preferred in amounts of 0.01 to 5, in particular 0.05 up to 2, especially 0.1 to 1 part by weight per 1,000 parts by weight A.
  • Preferred gas odorants can, for example, have the following compositions have:
