Vapor Pressure of RDX - Experimental and Correlation

This presentation discusses the vapor pressure of 1,3,5-Trinitroperhydro-1,3,5-triazine [RDX] available in the literature and current experimental data.  Experimental data have been collected using two techniques via Knudsen method and the Gas Chromatography-Retention Time [GC-RT] method.  The two techniques - Knudsen technique at low temperatures [320 -350 K] and GC-RT technique at high temperatures [400 - 495 K] were adopted to collect consistent, accurate vapor pressure data.  The current work has expanded the vapor pressure and temperature data for RDX, a well known explosive material.  The data should be useful in building sensors for detecting RDX.  The vapor pressure versus temperature data was fit to Antoine's equation resulting in the constants A = 34.88, B = 25418.7 and C = 310.88.
