Enthalpy of sublimation
| ΔsubH (kJ/mol) | Temperature (K) | Method | Reference | Comment |
|---|---|---|---|---|
| 79.4 ± 2.4 | 278. - 333. | ME | Monnier, Nuta, et al., 2009 | Authors state in the paper that the compound is a liquid at room temperature. Figure 3 in the paper shows that the plot of ln P versus 1/T is linear over the entire temperature range. The authors refer to the enthalpy as the enthalpy of sublimation. We have taken the value to be the enthalpy of vaporization given the authors’ statement that the compound is a liquid. The compound’s melting point temperature is unknown. |
