CHM 226 Recrystallization of Acetanilide Recrystallization is an important method used by chemists to purify solid compounds. Why is purification so important? Well, from a real world perspective, when a chemist conducts a chemical reaction as in (Scheme 1), it will rarely go to 100% completion, and will frequently produce byproducts. It is advisable to weigh one 10-15 mg test sample first. Then you may be able to estimate visually other test samples as needed. Test for solubility in 0.2 - 0.3 mL of each solvent. Record your observations in a table like the one shown on p. 1.
