ABSTRACT
New apparatus to measure liquid-liquid or solid-liquid equilibria by a synthetic method has been built and described. It was used to determine the liquid-liquid equilibrium curves for four binary mixtures of nitromethane + {heptyl methyl ether CH3OnC7H15, or ethyl hexyl ether C2H5OnC6H13, or pentyl propyl ether nC3H7OnC5H11, or dibutyl ether nC4H9OnC4H9}. The influence of position of the ethereal group onthe solubility curve has been discussed.
