Method of marking hydrocarbon liquids |
| abstract |
The invention concerns a method of marking a hydrocarbon liquid comprising the n nstep of adding to said liquid, as a tracer compound, a compound of Formula I or Formula II:n nwherein at least one of R 1 -R 6 in Formula I and at least one of R 7 -R 14 in Formula II is selected from:n i. a bromine or fluorine atom; ii. a partially or fully halogenated alkyl group; iii. a branched or cyclic C 4 -C 20 alkyl group; iv. an aliphatic substituent linking two positions selected from R 1 -R 6 in Formula I to one another or two positions selected from R 7 -R 14 in Formula II to one another; or v. a phenyl group substituted with a halogen atom, an aliphatic group or halogenated aliphatic groupn nand none of R 1 -R 6 in Formula I and none of R 7 -R 14 in Formula II being a sulphonate group or COOR 15 , where R 15 represents H, C 1 -C 20 alkyl, C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, C 3 -C 15 cycloalkyl or aryl. |
