Abstract: The GLC study on the thermodynamic properties of adduct formation between Ni[(C8H17O)2PS2]2 and ketones was reported.The equilibrium constants at the temperatureof 333.2~363.2K were determind and can de described by the empirical equation: lgK = -1.174 - 0.6791nc + (202.1nc + 495.0)/T ΔH and ΔS were calculated by the least square method.It was found that -ΔH andΔS increased linearly with the number of carbon nc in ketone molecules -ΔH = 9.48 + 3.87 nc (kJ/mol) -ΔS = 22.5 + 13.0 nc (J/K·mol)The nature of adduct bonds was explained by means of electro-static model.
