Definitions
- This invention relates generally to a composition comprising a colorless marker dye and a liquid petroleum product, and to a method for marking petroleum products.
- phthalein derivatives are known and used as markers in petroleum applications and other industrial applications such as paints and plastics.
- U.S. Pat. No. 6,002,056 describes the use of thymolphthalein, cresolphthalein and related compounds as markers for petroleum products.
- this reference discloses only compounds having two phenolic hydroxyl groups, and does not suggest the use of phthalein esters as markers.
- phthalein derivatives stem from their typically low solubility in petroleum products.
- phthalein markers can be removed from a marked petroleum product by extraction with water, either deliberately by one seeking to circumvent the marking, or as a result of contact of the marked petroleum product with water bottoms in storage tanks.
- the problem addressed by this invention is to find colorless marker dyes with improved solubility in petroleum products.
- the present invention is directed to a composition comprising a liquid petroleum product and a compound of formula I in an amount that is not detectable visually.
- R 1 is C 1 -C 18 alkyl, C 1 -C 18 alkenyl, aryl or aralkyl
- R 2 , R 3 and R 4 are independently hydrogen, C 1 -C 12 alkyl, chloro or bromo
- R 5 is hydrogen, chloro or bromo.
- the present invention is further directed to a method of marking a liquid petroluem product comprising adding to the petroleum product as a marker an amount of a compound of formula I that is not detectable visually, and wherein the marker develops a color on contact with a developing reagent.
- alkyl is a hydrocarbyl group having from one to eighteen carbon atoms in a linear, branched or cyclic arrangement. Substitution on alkyl groups of one or more halo, alkoxy, alkanoyl or amido groups is permitted; alkoxy, alkanoyl and amido groups may in turn be substituted by one or more halo substituents. Preferably, alkyl groups are unsubstituted.
- An "alkenyl” group is an “alkyl” group in which at least one single bond has been replaced with a double bond.
- An "aryl” group is a substituent derived from an aromatic compound, including heterocyclic aromatic compounds having heteroatoms chosen from among nitrogen, oxygen and sulfur.
- An aryl group has a total of from five to twenty ring atoms, and has one or more rings which are separate or fused. Substitution on aryl groups of one or more halo, alkyl, alkenyl, alkoxy, alkanoyl or amido groups is permitted, with substitution by one or more halo groups being possible on alkyl, alkenyl, alkoxy, alkanoyl or amido groups. Preferably, aryl groups are unsubstituted or are substituted only by halo or alkyl groups.
- An "aralkyl” group is an "alkyl” group substituted by an "aryl” group.
- R 2 , R 3 and R 4 are hydrogen or alkyl having from one to four carbon atoms. It is also preferred that R 1 is alkyl having from one to four carbon atoms. It is preferred that R 5 is hydrogen.
- the liquid petroleum product is gasoline, diesel fuel, jet fuel, fuel oil, kerosene or lamp oil. It is preferred that the compound of formula I is present in an amount from 0.5 ppm to 100 ppm, and further preferred that it is present in an amount from 0.5 ppm to 10 ppm. It is preferred that the compound of formula I is prepared as a mixture with a high-boiling hydrocarbon-soluble solvent.
- Preferred solvents include 1-octyl-2-pyrrolidone, mixed methylnaphthalenes (sold as AROMATIC 200 by Exxon Corporation) or aromatic hydrocarbon solvents. The preferred concentration of the marker in the solvent is from 20% to 30%.
- the developing reagent is a strongly basic reagent, e.g., a hydroxide of an alkali metal or of a quaternary ammonium ion.
- the reagent is a quaternary ammonium hydroxide.
- This invention is further directed to the compound of formula I in which R 1 is propyl, R 2 is methyl, and R 3 , R 4 , and R 5 are hydrogen. Preparation of this compound is described in Example 1.
- a marker solution was prepared by dissolving a 100 mg portion of the residue in xylenes (100 mL), and diluting 1 mL of the resulting solution to 100 mL with kerosene to make a 10 ppm solution.
- a developer was made by dissolving 1g of a 40% solution of benzyltrimethylammonium hydroxide in methanol in 99 g of 2-ethyl-1-hexanol. To a 10 mL portion of the 10 ppm marker solution prepared above was added 2.5 mL of the developer. After the mixture was shaken for a few seconds, it acquired a blue-purple color. If necessary, quantitative determination of the marker concentration can be accomplished by measuring the absorbance of the solution at a wavelength of 581 nm.
