Method for producing ketazine |
| abstract |
(57) [Summary] [Objective] To provide an industrially convenient and economically advantageous production method for producing ketazine continuously and stably. In a method for producing ketazine from hydrogen peroxide, ammonia and a ketone in the presence of a catalyst-containing working fluid, the working fluid to be recycled and reused is purified by a cation exchange resin and an anion exchange resin, The impurities that adversely affect the reaction are removed to keep the reaction stable for a long time. |
