ΔfH°gas | -27.3 ± 1.3 | kcal/mol | Review | Martinho Simões | Selected data. The enthalpy of formation relies on -428.51 ± 0.45 kcal/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 | -23.6 ± 1.6 | kcal/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 | -39.13 ± 0.88 | kcal/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 | -34.4 ± 2.2 | kcal/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 | -23.9 ± 1.2 | kcal/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. |
