ABSTRACT:
Tagging compounds (which function as both dyes and markers) having the following structures: ##STR1## wherein x is an integer between 0 and 3 inclusive, y is an integer between 1 and 3 inclusive, z is 0 or 1, and R is a straight or branched chain hydrocarbon having from 1 to 5 carbon atoms are disclosed. These compounds can be dissolved in a diluent at a concentration of from about 10 percent to about 30 percent, forming a concentrate which can be further dispersed in an organic liquid to form a final concentration of from about 1 ppm to about 15 ppm of said tagging compound in said liquid. Methods for detecting the presence of a tagged compound in an organic liquid are also disclosed.
