IMS detection of chemical markers in petroleum products
View Patent ↗A method and composition for identifying chemically tagged petroleum products can be achieved by adding one or more chemicals to a selected petroleum product wherein the chemical is immune to extraction from the petroleum product by conventional inexpensive absorbents, cannot be removed by extraction with acids, bases, or immiscible solvents, cannot be easily oxidized, reduced or reacted with common agents, is difficult to disguise by masking with other agents, has a low polarity, and has a boiling point in the range of the petroleum product the chemical is being added to. The presence of the chemical is determined by using ion mobility spectroscopy.
1. A method for preparing a chemically tagged petroleum product, the method comprising the steps of:
identifying a plurality of containers containing a petroleum product to 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.
2. 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.
