Problems solved by technology

[0003] The traditional industrial synthesis method of ethylene bisfatty acid amide usually adopts a stirred reactor for batch operation in a single tank, which is easy to oxidize and color the ammonium salt intermediate produced, and the product has a deep color, which in turn leads to poor consistency and stability of the product. The popularization and application of this product in large-scale petrochemical installations and high-end fields will affect the market development of the product and the appearance of high added value, making it difficult to form a large-scale and intelligent industrialization technology
