실험 절차

A four neck flask (1 liter) equipped with a thermometer, a reflux condenser and a stirrer was charged with 86 g (0.5 mol) of benzenesulfonohydrazide, 0.95 g (0.005 mol) of p-toluenesulfonic acid and 700 ml of acetone and then heated under reflux for about 5 hours. The reaction liquid was cooled down to 20° C. or lower, and then crystal was filtered off and dried under reduced pressure, whereby white crystal was obtained.
