Thermochemistry of Solid Naphthalene Anion Salts and Their Interaction with Water

Calorimetric studies have been used to determine that the solid sodium salt of the naphthalene anion radical lies at about the same energy level as does sodium metal and naphthalene, while the tetrahydrofuran (THF) solvated anion radical lies 13 kcal/mol lower in energy.The solid potassium naphthalenide lies about 9.6 kcal/mol lower than solid potassium metal and naphthalene.The calorimetric results have been placed into a thermochemical cycle to yield the crystal lattice energy and the heat of solvation of the sodium salt.ESR has been used to monitor the decomposition of the solid anion radical salt into the sodium-naphthalene mixture
