| Abstract: | Densities of binary mixtures of polar organic solvents with alcohols were measured at 25‡C. The solvents studied were N,N-dimethylformamide,
dimethylsulfoxide, and formamide while alcohols were butanol, pentanol, hexanol, and 1,4-butanediol. Density measurements
of hydrocarbons (from pentane to dodecane and some heptane isomers) + N,N-dimethylformamide were also performed. From these
data the apparent molar volumes of alcohols and hydrocarbons as functions of concentration were calculated. The standard partial
molar volumes were obtained by extrapolation to infinite dilution and are discussed in terms of group contributions. |
