Quantity Value Units Method Reference Comment
Δfgas-114.1 ± 5.5kJ/molReviewMartinho SimõesSelected 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.
Δfgas-98.9 ± 6.8kJ/molReviewMartinho SimõesLiquid 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.
Δfgas-163.7 ± 3.7kJ/molReviewMartinho SimõesLiquid 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.
Δfgas-144.0 ± 9.1kJ/molReviewMartinho SimõesLiquid 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
Δfgas-100.0 ± 5.1kJ/molReviewMartinho SimõesThe 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.
