Process for separating and purifying substances by crystallization from the melt under high pressures In the process for separating or purifying substances by crystallization from melts or highly concentrated solutions under high pressures, gas is dissolved in the melt to be crystallized and is expelled again after the crystallization with reduction in the pressure. Still adhering or occluded impurities are thus removed.

Process for separating and purifying substances by crystallization from

In the process for separating and purifying substances by crystallization from the melt under pressure, the melt is subjected to pressure under an inert gas atmosphere and then cooled, whereupon it crystallizes. The residual melt is separated from the resulting crystals, after which the crystals are degassed by reducing the pressure and are caused to sweat, and the sweat oil is separated off.
