Research progress of micro-chemical technology in the synthesis of water treatment chemicals

This article reviewed the research progress of micro-chemical technology, especially micro-reaction technology, in the field of water treatment chemical synthesis. The focus was on the synthesis of polycarboxylic acid scale inhibitors and dispersants such as polyacrylic acid and polymaleic anhydride, benzotriazole and organophosphine corrosion inhibitors, organic sulfur and peroxide fungicides, as well as water clearing agents, defoamers and other products by using this technology. As a new green synthesis technology, micro-chemical technology was still mainly explored in the synthesis of water treatment chemicals. In terms of cost, it still lacked advantages, and it was still far from practical industrial application. However, its advantages of being green, safe, and efficient were in line with the trends of carbon reduction, environmental protection, safety, production integration and automation. With the advancement of micro-reactor technology, further reduction of costs, and the needs of social development, micro-chemical technology would have great application potential in the synthesis of water treatment chemicals and might rapidly promote its technological progress.
