Abstract

Данное изобретение относится к способу получения метилэтилкетоназина, который включает: (a) взаимодействие аммиака, перекиси водорода и метилэтилкетона в присутствии рабочего раствора с получением азина; (b) разделение рабочего раствора и азина, возможно содержащего метилэтилкетон, который не прореагировал, и 2-бутанол; (c) рециркулирование рабочего раствора на стадию (a) после необязательной обработки; (d) отделение метилэтилкетона и 2-бутанола от азина. 2-Бутанол, содержащийся в потоке со стадии (d), либо удаляют, либо дегидрируют до МЭК и рециркулируют на стадию (a).Международная заявка была опубликована вместе с отчетом о международном поиске.
