Abstract

In this paper, we examined the possibility of using high performance thin layer chromatography for the qualitative and quantitative determination of Centralites 1 (1,3-diethyl-1,3-diphenylurea) and 2 (1,3 dimethyl-1,3-diphenylurea). For this purpose, we developed new method in which we find an appropriate mixture of carrier solution, as a key factor in the development of the method, using a mixture of toluene, acetone and cyclohexane. We confirmed in the experiment that mixtures of 9 vol. toluene and 1 vol. acetone for Centralites 1 or 2, and 4 vol. toluene and 6 vol. cyclohexane for diphenylamine stabilizer, are appropriate. Experiments have shown that this method can be used in the testing of propellants, tested on mine caliber of 120 mm. The results of the experiment are proved by high performance liquid chromatography method. The results obtained by experiment, in combination with other analytical methods such as the vacuum stability test (VST), can be successfully used to predict the stability of propellants, which was further confirmed by the qualitative thin layer chromatography (TLC) method. Eight samples of mine 120 mm were tested and the maximum deviation of HPTLC results from HPLC was 0.04%. The results obtained are fully usable for predicting the life of the tested propellants.

Keywords:Centralite 1; centralite 2; high performance thin layer chromatography; mine 120 mm; propellant; propellant stability
