The energy of combination of crystalline boron in gaseous fluorine was measured in a bomb calorimeter. The experimental data combined with reasonable estimates of all known errors may be expressed by the equation: B ( c ) + 3 / 2 F 2 ( g ) = BF 3 ( g ) , Δ H f 298 ° = - 271.03 ± 0.51 kcal mol - 1 This result is compared with other recent work on and related to the heat of formation of boron trifluoride.
