3 (g) + (l) = AlH3O3 (amorphous) + 3 (g)
By formula: 3H2O (g) + C6H15Al (l) = AlH3O3 (amorphous) + 3C2H6 (g)
|rH°||-647.3 ± 6.3||kJ/mol||RSC||Fowell, 1961||Please also see Cox and Pilcher, 1970. 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.|
