ABSTRACT
Relative permittivities for the galactose + glycine + water solution have been measured from (278.15 to 313.15) K. Results indicate that the logarithmic values of the relative permittivities for the glycine + water solution increase with increasing molalities of glycine and decrease as the temperature rises. At given molalities, the relationship of the relative permittivity to the temperature can be expressed by a quadratic equation. At given temperatures and compositions of glycine, the dependence of the relative permittivities on the mole fraction of galactose can be described by a linear equation. At a given temperature and composition of galactose, the relationship between the relative permittivities and the mole fraction of glycine can be expressed by a quadratic equation. An empirical equation is proposed and used to relate log ? for the ternary solution to the temperature and compositions of the solution.
