Definitions
- the present invention relates to the odorization of gas.
- City and coke oven gases obtained by thermal processes contained intensely smelling components and therefore had a strong intrinsic odor, so that escaping gas could easily be perceived.
- THT and Mercaptane are ideal for reliable gas odorization.
- sulfur dioxide is produced as a combustion product - only a little at each individual burning point, but a few hundred tons per year nationwide.
- the smell should be unpleasant and distinctive (from kitchen and
- Household odorous substances are excluded). It is said to cause an alarm association in people who smell leaking gas.
- the odorant should be as non-toxic as possible and must not form toxic combustion products.
- the odorant should have a high volatility and evaporate as residue-free as possible.
- a suitable odorant must neither condense at winter temperatures nor segregate nor adhere to metallic lines.
- the odorant should be stable in storage and chemically resistant to the gas and to the systems. It must neither promote corrosion nor attack conventional seals.
- Alkyl acrylates, vinyl or alkyl ethers and mixtures thereof JP 76-7481
- n-valeric acid optionally in combination with ethyl acrylate and / or triethylamine (JP 76-34 841)
- the new odorant can be added to the gas in the same order of magnitude as sulfur-containing compounds and does not produce any corrosion-promoting products during combustion.
- 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 4 -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 nitrogen compounds B primarily include compounds
- the nitrogen compounds B include, for example
- Lactones such as caprolactone
- Nitriles such as 2-nonenenitrile and compounds of the formula
- R 1 to R 4 independently of one another are hydrogen or C 1 -C 4 -alkyl, preferably methyl or ethyl.
- Preferred compounds (I) are e.g. 2-methylpyrazine, 2,3-dimethylpyrazine, 2,6-
- 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 A.
- the odorants can contain antioxidants, as described, for example, in Römpp-Lexikon Chemie Version 1.3.
- the antioxidants C are preferably used in amounts of 0.01 to 5, in particular 0.05 to 2, especially 0.1 to 1 part by weight per 1,000 parts by weight A.
- Preferred gas odorants can have, for example, the following compositions:
