Recrystallization Abstract: Technical grade aniline was reacted with acetic anhydride to give acetanilide a dark brown color‚ due to the presence of impurities. Crystallization of the crude product from water was combined with decolorization with activated carbon‚ furnished pure acetanilide as white flakes‚ melting point 112-115°C‚ yield 70.3%. Experimental: 2 grams of technical grade aniline and 15ml water were placed in a 125ml Erlenmeyer flask. Then‚ 2.5ml of acetic anhydride was
