The molar enthalpy of occlusion of the (lithium chloride + potassium chloride) eutectic salt in zeolite 4A at the salt melting temperature {Delta}{sub 9cc}H{sub m}(T{sub fus}) was measured using differential scanning calorimetry. It was found that up to a mole fraction of the salt x = 0.931 in the (salt + zeolite) mixture, which is near the expected zeolite occlusion limit, {Delta}{sub occ}H{sub m}(T{sub fus}) was negative and directly proportional to x . Thus, within this composition range, the partial molar enthalpy of occlusion of the (lithium chloride + potassium chloride) eutectic salt in zeolite 4A at the salt melting temperature is constant and equal to - (24 {+-}1)kJ {center_dot} mol{sup -1}.
