Heat balances in crystallization

Heat effects and heat balances in crystallization. When a compound whose solubility increases as temperature increases dissolves, there is an absorption of heat, called the heat of solution. An evolution of heat occurs when a compound dissolves whose solubility decreases as temperature increases. For compounds dissolving whose solubility does not change with temperature, there is no heat evolution on dissolution. Most data on heats of solution are given as the change in enthalpy in kJ/kg mol (kcal/g mol) of solute occurring with the dissolution of 1 kg mol of the solid in a large amount of solvent at essentially infinite dilution.
