Enthalpy of phase transition
| ΔHtrs (kJ/mol) | Temperature (K) | Initial Phase | Final Phase | Reference | Comment |
|---|---|---|---|---|---|
| 3.322 | 211.4 | crystaline, II | crystaline, I | Sorai, Tachiki, et al., 1971 | Two peaks were observed: at 211.4 K and 215.5 K, H and S give for overall transition. |
