✦ Synopsis

The thermal decomposition of phenyl carbazate results in formation of 4-amino urazole. The same compound is formed in reactions which according to other authors yield p-urazine. This six-membered cyclic isomer could not be prepared. The structure of 4-amino urazole is confirmed by study of infrared spectra and its reaction with acetone and benzaldehyde.

The reaction of urea with the carbohydrazide has also been studied.
