Resumen: Densities were measured for the N‐methylformamide–(C1–C10)alkan‐1‐ol and N,N‐dimethylformamide–(C1–C10)alkan‐1‐ol solvent mixtures at 298·15 K over the whole miscibility range (0<X1<1). The excess volumes (VE), which are discussed in terms of intermolecular interactions, are negative for the mixtures with the smallest alkanols in the series and increase with increase in the chain length. Comparison with other amide–alcohol mixtures previously investigated (formamide and pyrrolidin‐2‐one) indicates that the excess volumes are strongly influenced by the size of the alcohol and to a lesser extent by the nature of the amide. In contrast with the amide–water system, neither the amide size nor its degree of substitution plays an important role in the amide–alcohol systems investigated.
