Fractional crystallization (chemistry)
open-in-new
<p> In chemistry, fractional crystallization is a stage-wise separation technique that relies on the liquid–solid phase change. This technique <a href="/facts/Fractionation/85wUlYTN">fractionates</a> via differences in crystallization temperature and enables the purification of multi-component mixtures, as long as none of the constituents can act as solvents to the others. Due to the high selectivity of the solid–liquid equilibrium, very high purities can be achieved for the selected component. </p>
