摘　　要：灭多威生产过程中以水为溶剂,但灭多威在水中的溶解度较大,由此产生了大量含有灭多威的生产废水。以三氯甲烷作为萃取剂,从生产废水中萃取灭多威,灭多威的萃取率为95.20%,回收率为85.57%,纯度为98.14%。生产废水中回收的灭多威达到其产品主含量≥98.00%的质量指标要求。Water was used as the solvent in the production of methomyl,but methomyl has high solubility in water,resulting in a large amount of production wastewater containing methomyl.Using chloroform as the extractant,methomyl was extracted from production wastewater.The extraction rate of methomyl was 95.20%,the recovery rate was 85.57%,and the purity was 98.14%.The methomyl recovered from production wastewater met the product quality index requirements of main content≥98.00%.
