摘要
研究了温度、酸碱度、Hg( )等因素对 ( NH2 ) 2 CSO2 与 Co2 +- NH3体系定向反应的影响 ,发现该体系同时存在单电子反应和双电子反应 ,并相互竞争 ,( NH2 ) 2 CSO2 的双电子反应率随着体系温度、p H值增大和 Hg( )离子的加入而增高 .探讨了反应机理 ,并对两种反应的变化方向作了机理解释 .
The influence of temperature, pH value and Hg(Ⅱ) on the directional reaction of thiourea dioxide with [Co(NH 3) 6] 2+ was studied. The reaction of thiourea dioxide with [Co(NH 3) 6] 2+ prefers to one electron reaction. Simultaneously, two electron reaction exits partially. The fraction of two electron reaction of thiourea dioxide increases as raising temperature, pH value and adding Hg(Ⅱ). The reaction mechanism of this system was also suggested.
