Specific naphthalene derivatives are used to mark hydrocarbon liquids such as mineral oil and kerosene. The marker group includes the 2-methoxy and 2-ethoxy and 2-isobutoxy naphthalene derivatives along with deuterated isomers/analogs. The combination of deuterated isomers into a given non-deuterated marker to give a marker with a unique isotopic composition can be used as a means of coding a liquid for identification and for tracking and tracing purposes. The distinctive fragrant properties of the alkoxynaphthalene markers can be employed as a screening method for the detection of marked fuel in the field using the olfactory senses of humans or specially trained animals. |
