The atomic economic response emphasizes that the synthesis method should have the principle of “atomic economyâ€, that is, the atoms participating in the reaction process should be allowed to enter the final product as much as possible; in the synthesis method, substances that are toxic to human health and the environment should not be used or generated as much as possible; Chemical products with high use efficiency and low environmental toxicity; as far as possible without auxiliary substances such as solvents, they must be harmless when they have to be used; the production process should be carried out under mild temperature and pressure with the lowest energy consumption; try to use renewable Raw materials, in particular, biomass instead of petroleum and coal and other mineral raw materials; minimizing byproducts; using highly selective catalysts; chemical products can be degraded into harmless materials after use and can enter the natural ecological cycle; Technology to monitor the formation of hazardous substances; choose to participate in the chemical process of the material, to minimize the risk of accidents.
It can be seen that applying the principle of atomic economic response can stop pollution from the source, instead of treating pollution at the end. It can solve the hot issues of energy saving and emission reduction, and will certainly become the development direction of the chemical industry in the 21st century.
Atomic economic response is one of the important contents of green chemistry and has become a hot spot in modern synthetic chemistry. The American chemical industry regards “the greenization of chemistry†as one of the main directions for the development of the chemical industry in the 21st century, and has awarded the “Presidential Green Chemistry Challenge Award†to the latest achievements in the field of green chemistry. In China, the National Natural Science Foundation of China and the Chinese Academy of Sciences organized consultation activities on green chemistry and technology. Some of the research topics of green chemistry and chemical engineering have been incorporated into national major scientific and technological plans. The relevant institutions have also established green chemistry research institutes. However, the application of atomic economic responses in China is still limited. Some experts pointed out that with the tense oil resources and rising prices, the pace of the atomic economic response in the country will surely accelerate, and the difficulties in energy conservation and emission reduction will be overcome.

Atomic Economic Response: New Countermeasures for Energy Saving and Emission Reduction
The atomic economic response is the frontier field of international chemical science research today, and is the scientific foundation for the sustainable development of the chemical industry in the 21st century. Its purpose is to change the existing chemical production technology route from "pollution first, then governance" to "from the source Eradicating pollution has attracted more and more attention from governments, enterprises and academia. At present, one of the biggest tests facing the chemical industry is energy conservation and emission reduction. Insightful people have come up with new countermeasures for the “atomic economic response†by constantly reflecting on and summing up the relationship between chemistry, environment, and resources.
