Recrystallization of Acetanilide Using Water as Solvent

Abstract Recrystallization is a technique used to purify organic solids. This method involves dissolving of a solute in a solvent and inciting the solute to produce a precipitate from a solution. In this experiment, acetic anhydride was added to the mixture of 2mL aniline and 20mL of distilled water. The mixture was cooled in an ice bath and filtered through filter paper resulting to the crude acetanilide. The pure acetanilide was then produced by the filtered solution of crude acetanilide and recrystallizing solvent. Choosing of the recrystallizing solvent was done by placing a small amount of pure acetanilide in three test tubes, each containing: water, 95% ethanol and hexane. The final weight produced by the pure acetanilide is 1.1g contrary…
