Semimicroscale Experimental Procedure

Reagents and Equipment Using an automatic delivery pipet in the hood, 

54 M NaCN solution should be prepared by the instructor. 

CAUTION Sodium cyanide (NaCN) is extremely toxic. 

Attach the flask to a reflux condenser and mount the assembly in a sand bath on a magnetic stirring hot plate ( -). 

Reaction Conditions. Heat the mixture with stirring in a sand bath at 90-95 °C. Maintain this temperature for 30 min. The reaction solution turns yellow, and may then become cloudy within approximately 5 min.
