| titleOfInvention | Tracers and method of marking liquids |
| abstract | A method of marking a hydrocarbon liquid comprising adding to said hydrocarbon liquid a tracer compound, the tracer compound being a substituted biphenol ether having a core structure of Formula 1: Formula I wherein the two R groups are the same or different and selected from straight chain, branched or cyclic alkyl groups, phenyl or substituted phenyl groups, benzyl or substituted benzyl groups, or the two R groups form a single substituent linked intramolecularly to both oxygen atoms, and wherein one or both of the aromatic rings of the core structure is further substituted with at least one non-planar group. Preferably, the compound of Formula I is 2,2'-dipropyloxy-3,3',5,5'-tetra-(tert)-butylbiphenyl, 4,4'-dipropyloxy-3,3',5,5'-tetra-(tert)-butyl-4,4'-biphenyl or 4,4'-dioctyloxy-3,3',5,5'-tetra-(tert)-butyl-biphenyl. In another aspect, a method of identifying a source of a hydrocarbon liquid comprising analysing said hydrocarbon liquid to detect a tracer compound of Formula I and determining the source of the hydrocarbon liquid by the presence of the tracer compound. In yet another aspect, a hydrocarbon liquid comprising a tracer compound of Formula I. |
