二茂钛在水溶液和非水溶剂中电导行为的研究

Study of Conductance Behavior of Titanocene in Aqueous and Non aqueous Solvents

在25℃的二甲亚砜(DMSO)溶剂中,测定了二卤二茂钛,Cp_2TiX_2(C_P=环戊二烯基,或甲基环戊二烯基;X=F、Cl、Br、I)的当量电导,浓度范围为3.6～390×10^(-4)N。结果表明:Cp_2 TiX_2(X=Cl、Br、I)和(MeCp)_2 TiCl_2在 DMSO 中表现为1:1型电解质。纯水中,由于二茂钛发生水解,很难确定其电解质类型.

The conductance of titanocene dihalids in dimethyl sulfoxide was measured at 25℃ fosolute concentrations ranging from 3.6 to 390×10^(-4)N.All but titanocene difluoride are excellent in agreement with Onsager equation.The limiting equivalent con-ductance of each compound has been evaluated by an extrapolation of a plot of ■ versus ■.Because of titanocene hydrolysis,we cannot identify the titano-cene electrolyte type in aqueons solution.
