|fH°gas||-20.7 ± 1.1||kcal/mol||Review||Martinho Simões||Selected data. The enthalpy of formation relies on -452.03 ± 0.45 kcal/mol for the enthalpy of formation of Al(OOCMe)3(cr) and on 0.2 ± 0.05 kcal/mol for the enthalpy of solution of MeCOOH(l) in toluene Mortimer and Sellers, 1963. Liquid trimethylaluminum contains a very small molar fraction of monomer at 298 K, ca. 0.007% Smith, 1972, so that the "real" liquid should be described as [Al(Me)3]2.|

|fH°gas||-21.2||kcal/mol||Review||Martinho Simões||The enthalpy of formation was quoted from Smith, 1974 and relies on experimental data in Tröber and Stricker, 1966. Liquid trimethylaluminum contains a very small molar fraction of monomer at 298 K, ca. 0.007% Smith, 1972, so that the "real" liquid should be described as [Al(Me)3]2.|
