Abstract
THE thermochemical literature contains a single value1 for the standard enthalpy of formation ΔHf° P4O6(c) of −540 kcal/mole. This value was obtained by an indirect route involving accurate measurements of the heat of combustion of red phosphorus in nitric oxide. The products of combustion were reported to be exclusively P4O6 and P4O10, but the identification of the products was not necessarily definitive.
