Quantity | Value | Units | Method | Reference | Comment |
---|---|---|---|---|---|
ΔfH°liquid | -187.3 ± 5.1 | 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.; MS |
ΔfH°liquid | -172.1 ± 6.5 | 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.; MS |
ΔfH°liquid | -236.9 ± 3.1 | 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.; MS |
ΔfH°liquid | -217.2 ± 8.9 | 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; MS |
ΔfH°liquid | -173.2 ± 4.6 | kJ/mol | CC-SB | Tel'noi and Rabinovich, 1980 | Value corrected based on a set of ancillary data by J.A. 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.; MS |
