Vapor Pressure of Methylphosphonic Dichloride: A Compendium

摘要

Vapor-pressure data for methylphosphonic dichloride from many sources are reviewed and analyzed to obtain a best-fit predictive Antoine equation. Also given are the heat of vaporization and volatility at various temperatures. Zeffert published an Antoine equation for dichlor in 1960. However, no experimental data were given in the report. Several British technical reports contained some experimental vapor pressure data for dichlor, and several Edgewood Arsenal contractor reports also contained vapor-pressure data for the compound. The data from these various sources were combined into a set and evaluated, using Penski and Latour's method of computation. Zeffert's equation was used to calculate values for his experimental data and these values were used when all data were combined into a set.
