IMS detection of chemical markers in petroleum products

A method for preparing a chemically tagged petroleum product, the method comprising the steps of:

• identifying a plurality of containers containing a petroleum product so be tagged;
• and,
• adding to at least one of the containers a chemical with the general formula RCAR′,
• wherein R is a component selected from the group consisting of alkyl, olefin, aryl, and heterocycle;
• wherein R′ is a compound selected from the group consisting of alkyl, olefin, aryl, heterocycle and hydrogen;
• wherein A is a compound selected from the group consisting of ketones, alcohol, amines, cyano, sulfate, nitrile, nitrate, halogen, organic acid, mercaptan, aldehyde, formyl, thiocyano, and isothiocyano;
• and,
• wherein the chemical is encased in a permeable sphere.
