Liquid composition for marking liquid hydrocarbon fuels and other fuels for internal combustion engines, internal combustion engine fuels and other fuels containing the same, and process for detecting markers

摘要

The present disclosure includes liquid compositions that can be used for marking liquid hydrocarbon-based fuels and combustibles; these compositions include at least one marker, one or more solvents and, optionally, one or more functional additives other than the markers. The disclosure also includes a process for qualitative and quantitative detection of these markers present in a liquid hydrocarbon-based composition.
