Densities, refractive indices, viscosities, enthalpies, vapour–liquid equilibria, and surface tensions were determined for the n-pentane + dichloromethane system at 298.15 K. From the experimental results, excess molar volumes, excess viscosities, excess molar enthalpies, excess molar Gibbs free energies, and excess surface tensions were calculated. From these data, qualitative information could be obtained about the interaction between both chemical species.

Excess molar volumes in the benzene-tert-amyl methyl ether and cyclohexane-tert-amyl methyl ether systems were measured by a vibrating-tube densimeter at 298.15 K and compared with the data for the methanol-tert-amyl methyl ether system determined previously. Besides, the refractive indices in both the systems were measured at the same temperature.

The densities, refractive indices, and viscosities of liquid n-nonadecane and n-nonadecyl benzene were investigated at temperatures not too far above their respective melting points. Except for the viscosities, no significant differences were observed in the behavior of the two hydrocarbons. The n-nonadecane + n-nonadecyl benzene system exhibits small positive excess volumes and small negative excess viscosities. The excess refractive index is zero in the entire concentration range.
