실험 절차

Prilled urea (17.5 grams, 0.29 moles) was dissolved in 53.5 grams water. To this solution was slowly added sulfuric acid (29.0 grams, 0.26 moles, 89.3%) at 66° C. The temperature was maintained below 50° C. in a cooling bath during the addition. The final solution on titration with 0.5 N NaOH (phenolphthalein indicator) was 5.3 N, which is equal to the theoretical value.
