无母液、无废水生产乙酰甲胺磷新技术

The New Technology of Producing Acephate without Mother Liquor or Wastewater

采用氨气代替氨水进行中和,通过离心得到醋酸铵产品。引进高效增溶剂,通过反萃取去除溶剂氯仿层和母液中杂质,最终得到98%的高含量乙酰甲胺磷产品,生产过程中无废水和母液产生。

Neutralization of ammonia gas instead of ammonia water, with acetic acid, the ammonium acetate can be obtained through centrifugation. Then, introduce efficient solubilizer into the chloroform and the mother liquor; remove the chloroform layer and the impurities through counter extraction, 98 % rich fraction of acephate is ultimately obtained.
