Vapour pressure and boiling temperature

From the published literature [89,744,860,1514,1591] assembled by Stull [1971], the vapour pressure data of phosgene have been processed [1541] in the form of the Antoine equation. Equation (6.3)  

The calculated data are illustrated in Fig. 6.3(A) and 6.3(B) in the form of vapour pressure-temperature curves over the temperature ranges of -93 to 8.3 C, and 8.3 to 174 C, respectively. The experimental data according to Giaque and Jones for the more limited temperature range of -57.6 to 8.0 C (and from which the second set of Antoine 

Between ca. 100 Pa and standard atmospheric pressure, the vapour pressure of phosgene (based on the data of [1971]) can also be represented (T in K) by Equation (6.4) [2157]  

Although this equation fits the data that it was designed to represent, it must be noted that this equation suggests the boiling temperature of 8.3 C, which is now believed to be inaccurate. 

For the temperature interval 215 to 281 K, the data of Giaque and Jones [751] were represented by Equation (6.5)
