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。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,因此这类配物合的加合作用受到了广泛的注意。文献[4～6]利用气液色谱法测量了Ni[THDD]_2,Ni[(C_8H_(17)O)_2PS_2]_2与含氮有机碱加合反应的平衡常数,标准焓变和标准熵变值,得到了与 Dialkyl dithiophosphate and its transition metal complexes with strong bactericidal properties and inhibition of enzymatic hydrolysis, can be used as petroleum additives and polymer antioxidant, but also a class of excellent extractant for cobalt and nickel, Cobalt manganese and other extraction and separation. Adducts of metal dithiophosphates with nitrogen and oxygen-containing organic bases play an important role in liquid-liquid extraction, and thus the adventitious action of such ligand complexes has drawn much attention. In literature [4] and [6], the equilibrium constant, standard enthalpy change and standard entropy change of Ni [THDD] _2 and Ni [(C_8H_ (17) O) _2PS_2] _2 adduct with nitrogen- Value, got with
