Aldon® Innovating Science™ AP Chemistry kits offer cutting-edge science for the classroom! This kit helps science teachers teach science without the need for a lot of laboratory preparation. Enough materials for 15 setups. Includes teacher’s and student’s guides. Grades 9-12.

In a reaction vessel salicylic acid, acetic anhydride and sulfuric acid are mixed. The exothermic reaction will cause the temperature to increase to 70°-80° C. Once the reaction is complete the vessel is cooled in an ice bath and acetylsalicylic crystallizes out. This material is re-crystallized in toluene to purify the product. The product identity is confirmed by melting point. The mass of the re-crystallized product is used to determine the yield of the synthesis. In this experiment, you will perform the synthesis of acetylsalicylic acid (aspirin), purification by re-crystallization, and using melting point to confirm identity.

Kit includes:
• 2 x 25 ml - Acetic anhydride UN1715
• 1 x 15 g - Salicylic acid
• 2 x 25 ml - Sulfuric acid conc. UN1830
• 2 x 25 ml - Toluene UN1294
