摘要：
The excess molar enthalpies of (butan-1-ol or 2-methylpropan-2-ol + formamide or N-methylformamide or N,N-dimethylformamide) were measured with a flow microcalorimeter at the temperature 313.15 K. The excess enthalpies are negative for (2-methylpropan-2-ol + N-methylformamide) at low mole fractions of the amide and positive for the other mixtures. The results are discussed in terms of molecular interactions in the mixtures, especially those involving N-H protons. © 1991 Academic Press Limited All rights reserved.
