β¦ Synopsis
Ε½
Excess enthalpies have been measured for 2-methyoxyethanol q methyl 1,1-methylethyl . Ε½ . ether and for 2-methoxyethanol q n-heptane at the temperature 298.15 K. Smooth representations of the results are described and, in the case of the n-heptane mixture, are used to estimate the limiting mole fractions for the region of partial miscibility.
