Biphenyl recrystallization solvent

Websolubility in cold solvent. Solvents which exhibit the first two behaviors are not useful for recrystallizing a compound. A solvent showing the third behavior, that is, high solubility at high temperatures and low solubility at low temperatures, is one that is suitable for use as a recrystallization solvent. y-> temperature---> Good Bad Bad Webrecrystallization solvent contains two miscible solvents. The solid compound must be very soluble in one (solvent A) and nearly insoluble in the other (solvent B). Typically, the impure solid is dissolved in a hot solvent A, followed by addition of solvent B to reach saturation. At this point, seed crystals will form and grow.
