Atomic economy and "5R" principle are the core contents of green chemistry. Atomic economy refers to making full use of each atom in the reactant, so as to make full use of resources and prevent pollution.

Atomic utilization rate is detached, and each raw material can be used to the maximum extent and combined with the target product. The less waste produced by the reaction, the less pollution to the environment, and the five "R" principles of green experiment should be followed in the experiment process.

The ideal of green chemistry is to eliminate pollution from the source, make the whole synthesis process and production process friendly to the environment, no longer use toxic and harmful substances, no longer produce waste and no longer treat waste, which is the fundamental countermeasure to eliminate pollution.

Because scientific pollution prevention measures have been adopted from the beginning, the process and terminal are zero emissions or zero pollution. Many countries in the world regard "green chemistry" as one of the main directions of chemical progress in the new century.

199 1 year, "green chemistry" became the central slogan of the US Environmental Protection Agency, and established the important position of green chemistry. At the same time, the Office of Pollution Prevention and Toxicology of the U.S. Environmental Protection Agency launched the research fund plan of "Changing the synthetic route to prevent pollution", with the purpose of funding research projects to prevent pollution in chemical design and synthesis.

1993, and the research topic is extended to green solvents, safe chemicals, etc. And changed its name to "Green Chemistry Plan". "Green Chemistry" has established various voluntary cooperation among academia, industry, government departments and non-governmental organizations, aiming at promoting the application of chemistry to prevent pollution.

RACI, the Royal Australian Institute of Chemistry, established the "Green Chemistry Challenge Award" in 1999. The award aims to promote the development of green chemistry in Australia, reward all kinds of easy-to-popularize chemical innovations and improvements developed to prevent environmental pollution, and commend units and individuals who have made great contributions to promoting green chemistry education.

China's activities in the direction of green chemistry have gradually become active. 1995, the Department of Chemistry of China Academy of Sciences decided on the consulting topic of "Green Chemistry and Technology", 1996, held a seminar on "Green Chemistry and Technology in Industrial Production" and published the Collection of Academic Reports of the Seminar on Green Chemistry and Technology.

During the Ninth Five-Year Plan period from 65438 to 0997, the National Natural Science Foundation of China and China Petrochemical Group jointly funded the major basic research project "Environmental Friendly Petrochemical Catalytic Chemistry and Chemical Reaction Engineering". The Center for Green Technology and Development of China University of Science and Technology held a forum in the school, and published a collection of papers on some major issues in current green technology.

In July 2006, the Green Chemistry Professional Committee of Chinese Chemical Society was formally established. The above activities promoted the development of green chemistry in China.
