Deltafsolid167.7 ± 4.1kJ/molReviewRoux, Temprado, et al., 2008There are sufficient literature values to make a qualified recommendation where the suggested value is in good agreement with values predicted using thermochemical cycles or from reliable estimates. In general, the evaluated uncertainty limits are on the order of (2 to 4) kJ/mol.; DRB
