WebMethods of purification of organic compounds by Crystallisation. Crystallization is the formation of a solid with highly organised atoms or molecules into a crystal structure. Crystals can form via various processes such as solution precipitation, freezing, and, in rare cases, direct deposition from a gas. WebCrystallization is the better method of separating the mixture than evaporation. This is because, on evaporation, some of the solid particles in mixture get decomposed leaving behind impurities whereas, in crystallization, pure crystals of solids are obtained.
