Method of marking hydrocarbon liquids |
摘要 |
A method of marking a hydrocarbon liquid includes the step of;
adding to the liquid, as a tracer compound, a compound of Formula I:
wherein at least one of R1-R4 is selected from:
i. a bromine or fluorine atom;ii. a partially or fully halogenated alkyl group;iii. a branched or cyclic C4-C20 alkyl group;iv. an aliphatic substituent linking two positions selected from R1-R4 in Formula I to one another; orv. a phenyl group substituted with a halogen atom, an aliphatic group or halogenated aliphatic group. The tracer compounds are resistant to removal from the fuel by chemical laundering or by contact with absorbents such as charcoal. |

1. A method of marking a hydrocarbon fuel or octane comprising the step of adding to said hydrocarbon fuel or octane, as a tracer compound in an amount of 1 ppbv to 1 ppmv of said hydrocarbon fuel or octane, a compound of Formula I:wherein at least one of R1-R4 is selected from a group consisting of:
i. a bromine or fluorine atom; ii. a partially or fully halogenated alkyl group; iii. a branched or cyclic C4-C20 alkyl group; iv. an aliphatic substituent linking two positions selected from R1-R4 in Formula I to one another; and v. a phenyl group substituted with a halogen atom, an aliphatic group or halogenated aliphatic group; and further wherein none of R1-R4 consists of a hydroxyl group or an amino group. |
