Abstract
Official abstract text for this publication.
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 R 1 -R 4 is selected from: 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 4 in Formula I to one another; or v. 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.
First claim
Opening claim text (preview).
The invention claimed is: 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 R 1 -R 4 is selected from a group consisting of: i. a bromine or fluorine atom; ii. a p…
