Vapor Pressure and Its Temperature Dependence of 28 Organic Compounds: Cyclic Amines, Cyclic Ethers, and Cyclic and Open Chain Secondary Alcohols

“…For piperazine, which is a solid at 298.15 K, the reported value is the enthalpy of sublimation. The virial coefficients were taken from Dymond et al or estimated by us with an uncertainty up to 1 dm 3 mol –1 for the least volatile compounds. The nonideality of the vapor phase, as measured by B 22 in eq affects Δ vap H by (0.02 to 0.5) kJ mol –1 , the largest value referring to the most volatile substances.…”

Interatomic Interactions Responsible for the Solid–Liquid and Vapor–Liquid Phase Equilibria of Neon

“…This is in contrast to the small but nonetheless easily discernable influence of the FH-2 term for SLE (see Figures –). Calculations including the FH-1 and FH-1 + FH-2 terms for B typically yield relative deviations from the experiment of ±2%, whereas much larger deviations are observed at low T for SAAP, particularly in the vicinity of the Boyle temperature ( T Boyle = 119.2 K) at which B = 0. We note that the recommended B values for neon that we used for this comparison differ significantly from the earlier recommended values .…”

The former values are generally in better agreement with our SAAP + FH-1 + FH-2 calculations than the latter.…”

“…Therefore, it is of interest to examine the effect of the addition of both the FH-1 and FH-2 terms on B for neon. Comparisons with the recommended experimental data are illustrated in Figure . The values of B for the 2B (SAAP) + FH-1 + FH-2, which are also summarized in the Supporting Information, were obtained using the identical calculation procedure reported previously .…”
