Definitions

  • the present invention relates to the use of carbonyl compounds for labeling hydrocarbons, hydrocarbons containing carbonyl compounds as labeling agents, and to a method for detecting carbonyl compounds in hydrocarbons.
  • hydrocarbons e.g. Products from the refining of petroleum
  • heating oil is usually marked, since it is taxed much less than that which is identical in composition to diesel oil.
  • Suitable marking agents for hydrocarbons should in particular
  • the object of the present invention was to provide new marking agents for liquid or liquefiable by compression hydrocarbons. Such markers should be readily available and have the property profile mentioned above. 2
  • R 1 is hydrogen, -C 4 alkyl, -C 4 alkoxy or a radical of the formula
  • X is a direct bond
  • oxygen or imino and Z 1 and Z 2 are each independently hydrogen, C ⁇ -C 4 -alkyl, C ⁇ -C 4 -alkoxy or halogen,
  • R 2 is hydrogen, -CC 4 alkyl or a radical of the formula
  • R 3 is hydrogen, hydroxy, -CC 4 alkyl or -CC 4 alkoxy and
  • L 1 and L 2 each independently represent hydrogen, hydroxy, C 1 -C 4 alkyl, C 1 -C 4 alkoxy or halogen and
  • the ring A can be benzo-fused, advantageously for labeling hydrocarbons.
  • R 1 , R 2 , R 3 , L 1 , L 2 , Z 1 and Z 2 are, for example, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl or tert-butyl.
  • R 1 , R 3 , L 1 , L 2 , Z 1 and Z 2 are, for example, methoxy, ethoxy, propoxy, isopropoxy, butoxy, isobutoxy, sec-butoxy or tert-butoxy.
  • L 1 , L 2 , Z 1 and Z 2 are, for example, fluorine, chlorine or bromine.
  • Labeling in the sense of the invention means an addition of the carbonyl compounds of the formula I and / or II to hydrocarbons, the hydrocarbons thereby not being visible to the human eye, but the carbonyl compounds of the formula I and / or II being changed by the here Detection methods described in more detail are easily and clearly visible.
  • Hydrocarbons in the sense of the invention are generally understood to mean products such as are obtained in the refining of petroleum. These are e.g. Propane, butane, pentane, hexane, heptane, octane, isooctane, benzene, toluene, xylene, ethylbenzene, tetralin, decalin or dimethylnaphthalene.
  • these are mineral oils, for example fuels, such as gasoline, kerosene or diesel oil, or oils, such as heating oil or motor oil.
  • this also includes products such as those used for processing certain types of plants, e.g. Rape or sunflowers. Such products are also known under the term "bio-diesel”.
  • the hydrocarbons are generally in the liquid state under normal conditions or are in the gaseous state and are e.g. by compression, liquefiable, e.g. Liquefied petroleum gas, such as propane or butane.
  • Carbonyl compounds of the formula I are preferably used, in which R 1 is C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy or a radical of the formula
  • Z 1 and Z 2 each have the meaning given above, and R 2 is C ⁇ -C-alkyl, as a marking agent.
  • the carbonyl compounds of the formula I and / or II are used either in bulk or in the form of solutions.
  • Organic solvents are suitable as solvents.
  • Aromatic hydrocarbons such as toluene, xylene, dodecylbenzene, diisopropylnaphthalene or a mixture of higher aromatics, which is commercially available under the name Shellsol AB (Shell), are preferably used.
  • Shellsol AB Shellsol
  • alcohols such as methanol, ethanol, propanol, isopropanol, butanol, isobutanol, pentanol, hexanol, heptanol, octanol, 2-ethylhexanol or cyclohexanol
  • glycols such as butylethylene glycol or methylpropylene glycol
  • amines such as triethylamine, diisooctylamine, dicyclohexylamine, aniline, N-methylaniline, N, N-dimethylaniline, toluidine or xylidine
  • alkanolamines such as 3- (2-methoxyethoxy) propylamine, o-cresol, m-cresol, p-cresol, ketones , such as diethyl ketone or cyclohexanone, lactones such as ⁇ -buty
  • the hydrocarbons preferably have a content of 5 to 1000 ppm, in particular 10 to 1000 ppm, of marking agent. Particularly noteworthy is a content of 10 to 500 ppm, in particular 50 to 100 ppm.
  • the hydrocarbons can also contain other labeling or denaturing agents known per se, such as furfural or C.I. Solvent Red 198 included.
  • carbonyl compounds of the above formulas I and / or II can advantageously be detected in hydrocarbons if the hydrocarbons are treated with an aqueous-alcoholic or aqueous-acetone solution of an iron (III) salt.
  • Suitable iron (III) salts are e.g. Iron (I ⁇ I) halides, such as iron (III) chloride or iron (III) bromide, iron (III) sulfate, iron (III) nitrate or iron (III) acetate.
  • Iron (I ⁇ I) halides such as iron (III) chloride or iron (III) bromide, iron (III) sulfate, iron (III) nitrate or iron (III) acetate.
  • ferric chloride is preferred.
  • the iron (III) salts are used in an aqueous-alcoholic or aqueous-acetone solution.
  • the use of an aqueous-alcoholic solution is preferred.
  • Suitable alcohols for the preparation of the aqueous-alcoholic solution are e.g. Methanol, ethanol, propanol or isopropanol.
  • Methanol e.g. Methanol, ethanol, propanol or isopropanol.
  • methanol or ethanol is preferred, the use of methanol being particularly noteworthy.
  • suitable reagent solutions generally have a content of 0.05 to 0.5% by weight, preferably 0.1 to 0.3% by weight, iron (III) salts, 10 up to 90% by weight, preferably 40 to 70% by weight, of an alcohol or acetone and 10 to 90% by weight, preferably 30 to 60% by weight, Water, the total of the components of course giving 100 wt .-%.
  • the detection is usually carried out by vigorously shaking about 20 ml of labeled hydrocarbon with about 2 ml of reagent solution for about 15 to 20 seconds.
  • the phase is allowed to separate.
  • the lower aqueous phase has a red or violet-brown color. The color depends on the type of marking agent.
  • the content of the marking agent can be determined by methods known per se, e.g. by means of spectroscopic methods.
  • the detection is usually carried out in such a way that in a suitable container, e.g. a test tube, 1 to 2 ml of reagent solution and then drains the liquefied hydrocarbon from a gas bottle containing the liquefied hydrocarbon for about 15 to 30 seconds and collects it in the container.
  • a suitable container e.g. a test tube
  • the hydrocarbon escape from the lying bottle, since in this case it will generally still emerge in the liquid state.
  • the liquefied hydrocarbon is allowed to evaporate.
  • the reagent solution In the presence of the carbonyl compounds of the formula I and / or II, the reagent solution then has a red or violet-brown color.
  • Example 1 was carried out with unmarked liquid gas.
  • the reagent was yellow in color.
  • Example 2 The test described in Example 1 was repeated. The reagent was clearly purple in color.
  • Example 5 20 ml of diesel oil marked with 50 ppm acetylacetone were placed in a separatory funnel. Then 2 ml of the reagent described in Example 1 were added and the mixture was shaken vigorously for 20 seconds. They were then allowed to sit down. The phases separated after 5 minutes. The lower aqueous phase was clearly red in color.

The lower aqueous phase was clearly red in color. Example 5
  • Example 4 1 ml of the labeled diesel oil from Example 4 was diluted with 9 ml of unlabeled diesel oil. The procedure described in Example 4 was repeated with this mixture. The lower aqueous phase was slightly red in color.
  • Example 4 The procedure described in Example 4 was carried out with 20 ml of unlabeled diesel oil. The lower aqueous phase remained yellow.
