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.
