Thermochemical behavior of mixtures ofN,N-dimethylformamide with dimethylsulfoxide, acetonitrile, andN-methylformamide: Volumes and heat capacities
Densities and molar heat capacities have been measured for mixtures ofN,N-dimethylformamide with dimethylsulfoxide, acetonitrile, andN-methylformamide at 25°C over the complete mole fraction range. From these dat...

Volumes and heat capacities of water andN-methylformamide in mixtures of these solvents
The densities of mixtures ofN-methylformamide (NMF) and water (W) have been measured at 5, 15, 25, 35, and 45°C, and the heat capacities of the same system at 25°C, both over the whole mole-fraction range. From t...
