Green chemistry technology is a new technology in the field of chemical production. Mainly engaged in design, products and processes, through science and technology to optimize chemical reactions, reduce the use and production of harmful substances. Green chemical technology is widely used in manufacturing engineering, biological engineering, metallurgical engineering and other fields. It can greatly reduce the use of raw materials in chemical production and improve the utilization rate of resources. The technology can also be used for the different chemical compositions of different products, and the waste and pollutants generated during chemical production can be recovered and used as a renewable resource. The existing chemical processes can be improved to reduce the environmental pollution caused by chemical processes. In the long - term development of chemical industry, the application of green chemical technology will become more and more important. In order to make effective use of green chemical technology, it is necessary to understand the relevant content.
