USE OF LEUCOTRIARYLMETHANES FOR MARKING HYDROCARBONS |
| 摘要 |
The invention concerns the use, as markers for hydrocarbons, of leucotriarylmethanes of formula (I) in which Z is an aromatic carbocyclic or heterocyclic group and R1, R2, R3 and R4 are hydrogen, optionally substituted C1-C16 alkyl, optionally substituted phenyl or optionally substituted naphthyl. The invention also concerns hydrocarbons containing such leucotriarylmethanes and a method of detecting leucotriarylmethanes in hydrocarbons.
