| titleOfInvention | METHOD AND APPARATUS FOR PREPARING HUDRAZO-DICARBONAMIDE USING UREA AS INITIAL MATTER. |
| abstract | The present invention relates to a method and apparatus for preparing hydrazodicarbonamide using urea as an economically and environmentally desirable starting material. The apparatus includes a pyrolysis furnace to obtain biuret and ammonia when pyrolizing urea, a recrystallization reactor to purify the biuret obtained from the pyrolysis furnace; a first reactor to obtain a metal monohalobiuret salt by reacting the biuret with metal hypohalogen compound or with halogen and base; a second reactor to synthesize the hydrazodicarbonamide by reacting the monohalobiurte salt with ammonia; and an ammonia evaporator to separate excess ammonia from hydrazodicarbonamide and supply the separated ammonia to an ammonia concentrator. |
