Enthalpy of vaporization
| ΔvapH (kJ/mol) | Temperature (K) | Method | Reference | Comment |
|---|---|---|---|---|
| 22.4 | 214. | A | Stephenson and Malanowski, 1987 | Based on data from 201. to 227. K. See also Fawcett and Lipscomb, 1964 and Dykyj, 1970.; AC |
Antoine Equation Parameters
log10(P) = A − (B / (T + C))
P = vapor pressure (bar)
T = temperature (K)
