Abstract:

N,N-diisopropylcarbodiimide, also known as DICDI, is a stabilizer for chemical warfare nerve agents such as VX and GD. The vapor pressure of DICDI was measured using complementary methods that allow data collection at ambient and high temperatures using gas saturation and differential scanning calorimetry, respectively. A three-parameter Antoine correlation equation based on the new data was determined. The resulting calculated values compared favorably to published and unpublished data cited in this report. This report includes derived properties, such as volatility, temperature-dependent heats of vaporization, normal boiling point, and entropy of vaporization.
