- 中文摘要: The stoichiometry of charge-transfer complexes which ionise in polar media has been studied by conductimetric titration technique in the systems morpholine-p-chloranil (CA), piperidine-CA and pyrrolidine-CA in three different polar solvents namely N,N-dimethylformamide, acetonitrile and dimethylsulfoxide at different temperatures of 10, 15, 18, 20, 25 and 30 °C. The stoichiometric ratios of these complexes were found to vary from 1:1 to 1:4 (acceptor: donor) depending on the system, temperature and solvent used. The asM-values of these complexes have been reported. The effect of solvents, temperatures and types of electron donors on the sP-values has been examined.
