Heating oil labeling

As heating oil branding is called the mark of tax-privileged fuel oil with dyes to confusion with diesel fuel to avoid. The middle distillates (light heating oil and diesel fuel) are chemically similar. Heating oil extra light (HEL), for example, only differs from diesel fuel in that it has a higher sulfur content. In the European Union, heating oil has been labeled with 6 mg / l Solvent Yellow 124 since 2001 . Because this is not so easily visible to the human eye, many states keep coloring with a highly visible dye. In addition to heating oil, other tax-privileged fuels such as agricultural diesel or marine diesel oil are also colored in most countries .

history

The German Mineral Oil Tax Act , in its original version from 1964, prescribed the dye Sudan Red 7B (Solvent Red 19) for marking tax-privileged mineral oils ( e.g. heating oil ) . The compound is a powder dye and its processing has known disadvantages, e.g. B. Risk of exposure in production and processing, high consumption of solvents for the manufacture of the "packages" and time-consuming dissolving processes. With the approval of modified dyes, the Mineral Oil Tax Act 1977 was adapted to the current technical and industrial hygiene requirements. Liquid dyes have been used and processed since then. According to the current ordinance and specification of the Federal Ministry of Finance in the Mineral Oil Tax Act and TRGS 614 (restrictions on use for azo dyes that can be split into carcinogenic aromatic amines) for marking mineral oil, a liquid dye is used that consists of two components (CAS numbers 56358-09-9 "N" - (2-Ethylhexyl) -1 - [[2-methyl-4 - [(2-methyl-phenyl) azo] phenyl] azo] naphthalen-1-amine and 57712-94-4 1- [ [2-methyl-4 - [(2-methylphenyl) azo] phenyl] azo] - "N" - tridecylnaphthalen-2-amine). In addition, the dye Solvent Red 215 (CAS No. 85203-90-3) is used for mineral oil export . The liquid dye mentioned (CAS number 56358-09-9) is also imported into the Federal Republic of Germany for the same area of ​​application. In addition, to the knowledge of the AGS, mineral oils are imported from neighboring EC countries which, according to local regulations, contain the azo dyes Sudan IV (85-83-6), Solvent Red 164 (92257-31-3) or Solvent Red 215 (85203- 90-3) are colored. Since 2002, the EU has switched over to labeling with the yellow marker Solvent Yellow 124 (34432-92-3), the analytical detection of which is much less complex to carry out. Since Solvent Yellow 124 only insignificantly colors the heating oil, 4.1 to 4.9 mg / l of the azo dye mixture Sudan Red M 462 are added. Sudan red M 462 consists of the above-mentioned red dyes N -ethyl-hexyl- (tolylazotolylazo) naphthyl-2-amine and N- tridecyl-1- (tolylazotolylazo) naphthyl-2-amine and can split off the carcinogenic o -toluidine .
