Viscosities of some N-methylformamide– and N,N-dimethylformamide–(C 1 –C 10 ) alkan-1-ol binary mixtures have been measured at 298.15 K over the whole composition range. The excess viscosities Gibbs energies activation for viscous flow, compared with values other amide–alcohol mixed solvents, suggest that alcohol size does not play a significant role in mixture behaviour. aliphatic amides gave heteroaggregates to greater extent, lower self-association pure amides. An analysis terms solvent solubility parameters good agreement experimental results.
