EDTA tetrasodium water treatment chelating agent EDTA 64-02-8

Description :

　　The production methods of EDTA are mainly divided into four types based on the variable raw materials used: method, method, method, and alkyl acetonitrile method. The cost of raw materials is high, equipment corrosion is severe, process conditions are difficult to control, and product quality is unstable. Due to the rapid development of industry and low prices in the world, the variable raw materials used for producing EDTA have shifted, and their technical and economic feasibility is much better than that of traditional methods. Among them, the EDTA product of the method is the purest, but the process is relatively long, especially when dealing with the mixture. The stability of the raw materials using the ethyl cyanide method is poor. Although the feeding operation is simple, the subsequent process of treating activated carbon is cumbersome and the environment is unclean. The use of raw materials is safe and the advantage is that it can produce directly applicable tetrasodium solution in one step without any refining, or use it as a product (content 38%), or directly produce disodium salt. Therefore, this method is also known as the "one-step method". The process conditions of this method are mild: temperature 85-110. C， Pressure -0.005 to 0.02MPa (gauge pressure), feeding time 3-6 hours.
