The vapor pressures of explosives

The vapor pressures (VPs) of many explosive compounds are extremely low, so determining accurate values proves difficult. Many researchers, using a variety of methods, have measured and reported the VPs of explosive compounds at single temperatures, or as a function of temperature using VP equations. There are large variations in reported VPs for many of these compounds, and some errors exist within individual papers.This article provides a review of explosive VPs and describes the methods used to determine them. We have compiled primary VP relationships traceable to the original citations and include the temperature ranges for which they have been determined. Corrected values are reported as needed and described in the text. In addition, after critically examining the available data, we calculate and tabulate VPs at 25°C.

► A review of explosive vapor pressures and the methods used to determine them. ► Vapor-pressure relationships are tabulated values traceable to original citations. ► Reported are calculated vapor pressures at 25°C. ► Calculated values and their averages for compounds are critically discussed.
