APPLICATION OF LIQUID-CRYSTALLINE DETECTORS TO THE QUANTITATION OF PROPELLANTS STABILIZERS BY THIN-LAYER CHROMATOGRAPHY

The results of quantitative determinations of stabilizers in propellan ts are presented. Components of propellants' samples were separated by means of TLC method. Then, chromatograms were mapped onto liquid crys talline detectors - porous foils impregnated by p-pentyl-p'-cyanobiphe nyl. The temperatures of spots' appearance on liquid crystalline detec tor was measured as a function of quantity of determined substance. Me asurements of chemical stability for above 100 lots of different type propellants were conducted. The possibility of liquid crystalline meth od of TLC chromatograms visualization for propellants' quantitation wa s shown.
