Question

In the hood, place 100 mu L of aniline in a tared 10 times 75 mm (small) test tube. Place the test cube in a small beaker or Erlenmeyer flask to avoid spillage. Stopper the cube with a cork. Now, using a Pasteur pipet, add (with swirling) 0.5 mL of water, followed by three drops of concentrated HCI. Add 10 mg of decolorizing charcoal (we use the pelletized form, called Nonrit^TM) to the solution. Mix well, mindful not to crush the charcoal pellets. Using a Pasteur pipet, transfer the solution to a 3-mL conical reaction vial, being careful not to take any of the pelletized charcoal along. Use an additional 0.5 mL of water to rinse the test cube and charcoal, and transfer that to the reaction vial as well. Place a magnetic spin vane in the vial and attach an air condenser. Dissolve 150 mg of sodium acetate trihydrate in 0.5 mL of water in a 10 times 75 mm (small) test tube. Cork the cube and set aside in a small beaker or Erlenmeyer flask for use in a later step. Remove the air condenser from the vial containing the aluminum chloride, and add 150 mu L of acetic anhydride, followed quickly by addition of the previously prepared solution of sodium acetate. Reattach the air condenser and begin stirring. The reaction is very rapid, and the product should begin to precipitate almost immediately upon mixing of the reagents. Stir thoroughly to ensure proper mixing. Let the vial stand at room temperature for five minutes, and then place in an Ice batch for an additional ten minutes to complete the crystallization process. Collect the acetanilide by vacuum filtration using a Hirsch funnel. Rinse the conical vial with two 0.5 mL portions of cold water, and use the rinse to wash the collected solid. Pull air through the funnel for an additional ten minutes, and then allow the product to dry in your drawer in an open container until the next laboratory period. Weigh the dry crystals and determine the melting point and percent yield. Recrystallization of the product is usually not necessary; however, if your melting point is more than 10 degrees off of the literature value, you may recrystallize the acetanilide from hot water (it will take approximately 3 mL of water to dissolve 150 mg of acetanilide).
