WebRecrystallization. 1. Recrystallization is the most convenient method for purifying organic compounds that are solids at room temperature. Compounds obtained from natural sources, or from reaction mixtures, almost always contain impurities. The impurities may include some combination of insoluble, soluble and colored impurities. To WebRecrystallization is defined as the process in which grains of a crystal structure come in a new structure or new crystal shape. A precise definition of recrystallization is difficult to state as the process is strongly related to several other processes, most notably recovery and grain growth.
