Solid-liquid equilibria in the C12H22O11-Ca(OH)(2)-H2O system have been determined at 30 degrees C. Two phases C12H22O11.3Ca(OH)(2) and C12H22O11.2Ca(OH)(2) have been evidenced, and solubility (liquidus) curves have been determined. It is thus shown that these ternary phases exhibit incongruent solubilities at 30 degrees C. These solid phases were characterized using Infrared Spectroscopy (IR), Scanning Electron Microscopy (SEM) and Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES).
