Composite luminescent markers for fuels, the process of synthesis of luminescent markers, and the use of compound as luminescent markers

摘要

Composite luminescent markers for fuels, the process of synthesis of luminescent markers, and the use of luminescent compounds as markers to this invention refers to a luminescent markers for renewable fuels and the process of synthesis of these markers and use Of these markers.These markers are preferably used for the marking of biofuels, including biodiesel. Optionally, can also be used in the marking of diesel, ethanol, gasoline, biokerosene and kerosene.The quantities necessary for marking are bastantereduzidas which can be detected at concentrations of the order of ppb (parts per billion) using conventional analytical techniques. The present invention also describes the process of synthesis of these markers, which involves the steps of production and purification of the compounds.
