发明名称 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.

主权项 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.
