Solid organic compounds when isolated from organic reactions are usually impure; they are usually contaminated with small amounts of other compounds that are produced along with the desired compound. The purification of impure crystalline compounds is usually done by recrystallization from a suitable solvent or a mixture of solvents.. 44: 93 - 95 (2014) 93 ULTRASONIC STUDIES OF ANTIPROTOZOAL DRUG IN PROTIC AND APROTIC SOLVENTS AT 308.15 K S.
