Abstract
The viscosities and densities of NaBr, NaBPh4, Bu4NBPh4, Bu4NBr, Bu4NT and NH4Br solutions in N,N-dimethylformamide have been measured at 25 , 40, 55 and 70 degrees C. The experimental results have been analysed using the Jones-Dole and modified Masson's equations. Ionic viscosity B-coefficients have been analysed using dielectric friction theory an d structural contributions. Different mechanisms of ion influence on s olvent dynamic structure have been ascertained for single ions (Na+, B r-) and large organic ions (Bu4N+, BPh4-).
