1 T. W. Richards and F. Barry. Journ. Amer. Chem. Soc. , 37 (1915), 998.
LABORATORY EXPERIMENTS 143 The residue in the original flask contains some sodium and must be handled with care. Remove the material and add it in small pieces to ethyl alcohol or acetone in a beaker, waiting until all the sodium in each piece has been destroyed before adding another. Dilute with water (Care!) before pour- ing the solution into the sink. Rinse out the flask with alcohol before adding any water.
Sometimes c...rude amyl alcohol is used for destroying sodium residues. Its action is. Much slower, and, furthermore, globules of sodium are often found at the end of the main reaction coated with sodium amyl oxide, and their presence is sometimes not noticed until after water has been added!
QUESTIONS 1. Of what does the crust on the sodium consist?
2. Name some other liquids that might be used to cover the sodium in the bottle.
3. Why must the xylene be removed after making the " bird- shot " sodium?
4. Compare the molecular and structural formulas of ethyl benzene and the xylenes.
