Vapor Pressure Data Analysis and Correlation Methodology for Data Spanning the Melting Point

Abstract

Vapor pressure information is important for a number of reasons related to chemical and biological warfare defense applications. Since it is often impractical to measure data over the desired range of temperatures, it becomes very useful to develop correlations based on measured data to facilitate interpolation and extrapolation. Penski reported a detailed description of one method commonly used to correlate vapor pressure data. This report expands on that work by exploring the merits of a similar metric to correlate the experimental data. A problem that has arisen involves data that extends across the melting point of the analyte. This phenomenon has been observed for a number of compounds of interest recently, and the data can be difficult to correlate, particularly when liquid and solid phase data are recorded using different analytical methods. We present here a method to quantitatively correlate such data sets.
