Make sure the mouth of the flask, is fitted with a long air condenser and the mixture is gently re-fluxed, by heating the contents of the round bottom flask on a wire gauze. Crystal Composition of Glacial Acetic Acid at 16.5-degree C. Difference between Acetic acid and Glacial Acetic Acid: 1. Aniline is refluxed with glacial acetic acid in the presence of fused sodium acetate when acetanilide is obtained. A Rapid and Additive-Free Ruthenium-Catalyzed Reductive Amination of Aromatic Aldehydes. Result - Weight of the acetanilide crystals obtained = _____g. K. Ponmani, S. Durga, M. Gowdhamamoorthi, S. Kiruthika, B. Muthukumaran. Glacial acetic acid 6 mL 3. The mixture is poured while hot into 100 mL of cold water. Round bottom flask of 100 ml, wire gauze, tripod stand, burner, clamp, reflux condenser, stirrer, filter paper, beaker, pipette, electronic balance, iron stand, measuring cylinder, aniline (20 ml), acetic anhydride and glacial acetic acid mixture (40 ml), zinc dust. Now cool down the solution and filter it. These metrics are regularly updated to reflect usage leading up to the last few days. This article is cited by Cecilia E. Silvana Alvaro, Norma Sbarbati Nudelman. Martin Matschke, Katrin Knop, Rainer Beckert. The hitherto followed method of correlation of the reaction rates in terms of the structure−reactivity relationships is unsatisfactory and erroneous. Electronic Supporting Information files are available without a subscription to ACS Web Editions. Giancarlo Cravotto, Stefano Di Carlo, Bernd Ondruschka, Vander Tumiatti, Carlo Maria Roggero. Vigorous heating is must when mixture is added in ice cold water. So, glacial acetic acid is far better than the normal acetic acid. Preparation of acetanilide from aniline. Purpose of using zinc dust is to prevent oxidation of aniline during the reaction.
Thus, obtained acetanilide crystals are crude or not pure so a recrystallization process should be carried out. Preparation of acetanilide (i) Take a 100 ml clean and dry R.B.

Thus, formed acetanilide is recrystallized to get pure crystals.
Its Melting point is 115℃. Wash all the apparatus with distilled water carefully before starting the experiment.
Now fix the round bottom flask on the burner for heating the reaction mixture using a tripod stand, wire gauze and sand bath. Sun, Werner R. Thiel. International Journal of Chemical Kinetics.

To prepare acetanilide from aniline, glacial acetic acid (acetic anhydride) and zinc dust. Preparation acetanilide aniline. Aniline is refluxed with glacial acetic acid in the presence of fused sodium acetate when acetanilide is obtained. Users are M. Gowdhamamoorthi, A. Arun, S. Kiruthika, B. Muthukumaran. The chemical reaction involved in preparation of acetanilide is given below –.
Once all acetanilide is precipitated, filter the reaction mixture. Allow the filterate to cool.
