| titleOfInvention | A kind of energy-saving clean production method of high-purity glufosinate-ammonium |
| abstract | The invention discloses the energy-saving clean production method of a kind of high-purity glufosinate-ammonium, comprise the following steps: 1) with phosphine oxamate two saline solution as raw material, enter bipolar membrane electrodialysis system and carry out bipolar membrane electrodialysis process, salt room controls pH=2.5 ~ 3.5 and obtains the mixed solution of phosphine oxamate and phosphine oxamate one salt, and alkali room obtains aqueous slkali；2) crystallisation by cooling after being concentrated by the mixed solution of phosphine oxamate with phosphine oxamate one salt, obtains phosphine oxamate and crystalline mother solution, and crystalline mother solution is recycled into bipolar membrane electrodialysis system and carries out bipolar membrane electrodialysis process；3) phosphine oxamate is reacted with ammonia, prepare glufosinate-ammonium.The present invention first uses bipolar membrane electrodialysis technology to prepare phosphine oxamate, again phosphine oxamate is reacted with ammonia, prepare glufosinate-ammonium, without being acidified with acid, avoiding substantial amounts of abraum salt waste water to produce, the glufosinate-ammonium purity obtained is high, yield is high, and the present invention is without being diluted phosphine oxamate salt, current utilization rate is high, and the processed in units amount of film is greatly increased. |
