WebWhat is Recrystallization. The definition of recrystallization is a technique for the purification of compounds in which a compound is dissolved in a solvent and slowly cooled to form crystals, which are a purer form of the compound. Scientists use recrystallization to purify solids, typically products, from different chemical reactions. http://www.whxb.pku.edu.cn/EN/10.3866/PKU.WHXB202402242
