Методика

A mixture of 100 grams (1.0 mole) of hydantoin, 106 grams (1.0 mole) of benzaldehyde, 63 grams (1.0 mole) of ammonium formate, and 230 grams (5.0 moles) of formic acid were held for 3 hours at reflux temperature. After the cooling off, there were obtained 173 grams of 5-benzylidene hydantoin, corresponding to 92% of theory based on hydantoin.
