摘要
用光谱法研究了Ni[(C_6H_(11)O)_2PS_2]_2与咪唑,4-甲基吡啶,2,4-二甲基吡啶,2,2＇-联吡啶,乙胺,正丙胺,正丁胺和二乙胺的加合反应,测定了加合反应的平衡常数。平衡常数随着氮碱分子碱度增加而增大,随着氮碱分子空间位阻的增加而减小。讨论了几类氮碱加合反应平衡常数测定的处理方法。
Reactions and the additive equilibrium constants of Ni[(C6H11O)2PS2]2 with imidazole, 4-methylpyridine, 2,4-dimethylpyridine, 2,2'-bipyridine, ethylamine, n-propylamine, n-butylamme and diethylamine have been studied spectrophotometrically. The constants increase with basicity of nitrogen base and decrease with increasing steric hindrancr of nitrogen base. Variations of the calculated constants for additive reaction of nitrogen base have been discussed.
