Melt crystallization is an extremely selective process that allows pure crystal formation even in relatively impure melts. It is an economic, energy efficient alternative purification step in cases where standard distillation is unsuitable due to e.g. glose boiling isomers, azeotropic systems, heat sensitive products, products that tend to polymerize, explosive substances and more.
