Liquid−liquid equilibrium and critical phenomena in the ternary system water + 2-methoxyethanol
(methylcellosolve) + toluene have been studied by means of the visual polythermal method under
saturation pressure in the temperature range from 283 K to 383 K. The system is characterized, at all
temperatures, by the presence of a two-phase liquid−liquid equilibrium. The solubility data for twelve
temperatures are presented. The mutual solubility of the components increases with increasing
temperature. The temperature dependence of the critical solution (plait) point composition has been
established.
