| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| ΔfH°gas | -114.1 ± 5.5 | kJ/mol | Review | Martinho Simões | Selected data. The enthalpy of formation relies on -1792.9 ± 1.9 kJ/mol for the enthalpy of formation of Al(acac)3(cr). Liquid triethylaluminum contains a very small molar fraction of monomer at 298 K, ca. 0.1% Smith, 1967, so that the "real" liquid should be described as [Al(Et)3]2. |
| ΔfH°gas | -98.9 ± 6.8 | kJ/mol | Review | Martinho Simões | Liquid triethylaluminum contains a very small molar fraction of monomer at 298 K, ca. 0.1% Smith, 1967, so that the "real" liquid should be described as [Al(Et)3]2. |
| ΔfH°gas | -163.7 ± 3.7 | kJ/mol | Review | Martinho Simões | Liquid triethylaluminum contains a very small molar fraction of monomer at 298 K, ca. 0.1% Smith, 1967, so that the "real" liquid should be described as [Al(Et)3]2. |
| ΔfH°gas | -144.0 ± 9.1 | kJ/mol | Review | Martinho Simões | Liquid triethylaluminum contains a very small molar fraction of monomer at 298 K, ca. 0.1% Smith, 1967, so that the "real" liquid should be described as [Al(Et)3]2 |
| ΔfH°gas | -100.0 ± 5.1 | kJ/mol | Review | Martinho Simões | The enthalpy of formation was quoted from Tel'noi and Rabinovich, 1980 and relies on experimental data in Fic, 1966. Liquid triethylaluminum contains a very small molar fraction of monomer at 298 K, ca. 0.1% Smith, 1967, so that the "real" liquid should be described as [Al(Et)3]2. |
