| titleOfInvention | Method for preparing hydrazine hydrate |
| abstract | A method for preparing hydrazine hydrate comprising: (a) reacting ammonia, hydrogen peroxide and methyl ethyl ketone in a working solution to form an azine; (b) separating the working solution from a mixture comprising the azine, methyl ethyl ketone oxime and optionally the methyl ethyl ketone which had not reacted; (c) recycling the working solution to step (a) after an optional treatment; (d) hydrolyzing the azine to obtain hydrazine hydrate and regenerating the methyl ethyl ketone; (e) recycling to step (a) the methyl ethyl ketone. In step (d) the methyl ethyl ketone oxime is purged. |
