Excess molar volumes of N-methylformamide + tetrahydrofuran, + 2-butanone, + ethylacetate at the temperatures between 303.15 K and 318.15 K

Excess molar volumes, VmE, of N-methylformamide (NMF) + tetrahydrofuran (THF), NMF + 2-butanone (B) and NMF + ethylacetate (EA) have been determined at the following temperatures: 303.15 K, 308.15 K, 313.15 K, and 318.15 K. The results have been discussed in terms of hydrogen bonding. Excess molar volumes were fitted with Redlich-Kister equation.
