摘要: 二烷基二硫代磷酸酯及其过渡金属配合物具有强杀菌性能及抑制酶水解作用,可以用作石油添加剂和高聚物防老剂,又是一类优良的萃取剂,用于钴镍、钴锰等的萃取分离[1-2]。二硫代磷酸酯的金属盐与含氮、含氧的有机碱形成的加合物在液-液萃取中起着重要作用[3],因此这类配物合的加合作用受到了广泛的注意。

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.
