Abstract
The solubility of dodecane has been determined in formamide, and in mixtures of water with formamide, N-methylformamide (NMF), and dimethylformamide (DMF) by a radiotracer method at 15°, 25° and 35°. The solubility of dodecane increases as the concentrations of the amides increase. The standard free energies (ΔG°), partial enthalpies (ΔH°), and standard entropies (ΔS°), of solution of dodecane have been calculated for the various systems. Positive values of ΔG° and negative values of ΔH° and ΔS° decrease numerically as the concentrations of amides increase.Keywords
