Liquid-liquid equilibrium (LLE) data are reported for dimethyl carbonate + n-decane, + n-dodecane, + n-tetradecane, or + n-hexadecane at atmospheric pressure, between 277 K and the upper critical temperatures. The solubility curve of pure solid n-hexadecane In liquid dimethyl carbonate Is also presented. The coexistence curves are very asymmetrical with respect to mole fraction, the asymmetry Increasing with the size of the n-alkane The critical solution points vary almost linearly with the number of carbon atoms of the n-alkane. The data are used In the framework of regular solution theory to obtain the solublHty parameter of dimethyl carbonate.
