摘　　要：我国氮肥企业面临着转型升级的需求,草酰胺作为一种优质缓释氮肥,国内未见有工业化生产的报道。简要介绍了历年来草酰胺合成方法。随着国内煤制乙二醇技术日趋成熟,草酸二甲酯氨解反应条件比较温和,收率很高,原料相对便宜易得,是目前最有希望实现工业化生产的工艺技术路线。Domestic nitrogen fertilizer enterprises are facing the need for transformation and upgrading.As a high-quality slow-release nitrogen fertilizer,oxamide has not been reported industrially in China.This paper briefly introduces the synthesis methods of oxamide in recent years.With the gradual maturity of domestic coal-to-ethylene glycol technology,dimethyl oxalate ammonolysis reaction conditions are mild,the yield is high,and the raw materials are cheap and easy to obtain.It is currently the most promising process technology route for industrial production.
