An isothermal (30 °C) study of heterogeneous equilibria in the sucrose (C 12H 22O 11)–calcium hydroxide (Ca(OH) 2)–water system

► Isothermal 30 °C study of heterogeneous equilibria in C12H22O11–Ca(OH)2–H2O system. ► Solubility (liquidus) curves have been determined. ► Two phases C 12H 22O 11·3Ca(OH) 2 and C 12H 22O 11·2Ca (OH) 2 have been evidenced. ► This work shows that these ternary phases exhibit incongruent solubilities at 30 °C. Solid–liquid equilibria in the C 12H 22O 11–Ca(OH) 2–H 2O system have been determined at 30 °C. Two phases C 12H 22O 11·3Ca(OH) 2 and C 12H 22O 11·2Ca (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 °C. These solid phases were characterized using Infrared Spectroscopy (IR), Scanning Electron Microscopy (SEM) and Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES).
