VAPOR PRESSURES AND HEATS OF SUBLIMATION OF SOME HIGH MELTING ORGANIC EXPLOSIVES

Abstract

The Langmuir method was used to determine the vapor pressures and heats of sublimation of several high melting organic explosives. The temperatures at which each compound would have a vapor pressure of 10 to the minus seven torr are: (1) cyclotrimethylene trinitramine (RDX), 48.0C; (2) cyclotetramethylene tetranitramine, beta polymorph, 121.9C; (3) 2,4,6- trinitroaniline (TNA), 44.0C; (4) 1,3-diamino-2,4,6-trinitrobenzene, form I polymorph, (DATB-I), 79.8C; (5) 1,3,5-triamino-2,4,6-trinitrobenzene (TATB), 131.4C; (6) 2,2',4,4',6,6'-hexanitrostilbene (HNS), 170.6C. Within a series those compounds which form the strongest intermolecular hydrogen-bonds have the highest heats of sublimation.
