Abstract

Настоящее изобретение относится к способу получения гидразингидрата, в котором: (a) аммиак вводят в реакцию с перекисью водорода и метилэтилкетоном в присутствии рабочего раствора, в результате чего образуется азин; (b) отделяют рабочий раствор от азина, содержащего оксим метилэтилкетона и, возможно, метилэтилкетон; (c) возвращают рабочий раствор на стадию (a) после возможной обработки; (d) гидролизуют азин, получая гидразингидрат и регенерируют метилэтилкетон; (e) возвращают метилэтилкетон на стадию (a), отличающемуся тем, что на стадии (d) производят удаление оксима метилэтилкетона.Международная заявка была опубликована вместе с отчетом о международном поиске.
