摘要：
The invention concerns a method of detecting the presence of naphthylamines used as tracers in mineral oils, the naphthylamine being extracted by treating the mineral oil with an aqueous medium and coupled in the aqueous phase with a diazonium salt to form an azo-dye. The invention also concerns the use of special naphthylamines as tracers for mineral oils, as well as mineral oils containing these special naphthylamines.
