  • Production method of hydrazine hydrate(part 3)
    2022-01-07

    In this method, ketone imine is generated by the reaction of butanone (methyl-ethyl ketone) and ammonia, and then oxidized to oxazizone with H2O2, and then ammoniated to methyl-ketone nitrile. The latter is hydrolyzed into hydrazine and ketone, and the unreacted ketone can be recycled after purification.
