In many laboratories, investigations aimed at replacing diphenylamine (DPA, propellant stabilizer) with other, less harmful substances are being carried out. For instance, good effects have been obtained in experiments with triphenylamine (TPA), which cannot produce - due to its structure - carcinogenic nitroso derivatives. In this work, a new, cheap and fast method for testing stabilizing properties of propellant stabilizers that have been used or being developed is presented. It consists in dispersing a stabilizer within silica gel followed by the measurement of the stabilizer transformation kinetics during its nitration with nitrogen oxides. The method combined with thin layer chromatography (TLC) provides a fast evaluation of stabilizing effectiveness.
