This work presents a study of solidliquid equilibrium of sucrose in three different binary liquid mixtures, methanolethanol, methanolwater, and ethanolwater for the temperatures of 303 and 313 K covering the whole composition range of the binary liquid solution. The data are presented as a function of the dielectric constant of the binary liquid mixture taking into account the self-association of water and alcohol. From a dissolution phenomenon standpoint, it seems that the temperature is more important than the dielectric constant of the binary liquid solution for the solubility mechanism. For each temperature, it was observed that the sucrose solubility is directly proportional to the dielectric constant of the binary liquid mixture.
