Introduction to green chemistry:
Green chemistry is also called environment-friendly chemistry, environment-friendly chemistry and clean chemistry, that is, the design of chemicals and processes that reduce or eliminate the use of harmful substances.
Green chemistry involves organic synthesis, catalysis, biochemistry, analytical chemistry and other disciplines, with a wide range of contents. Green chemistry advocates using chemical techniques and methods to reduce or stop using and producing raw materials, catalysts, solvents and reagents, products and by-products harmful to human health, community safety and ecological environment.

The definition of green chemistry is constantly changing. When it first appeared, it more represented an idea and a wish. However, with the development of the discipline, it gradually tends to practical application in the constant development and change, and its development is closely related to chemistry.
Green chemistry is different from pollution control chemistry. The research object of pollution control chemistry is the chemical technology and principle of treating the polluted environment and restoring it to its original appearance. The ideal of green chemistry is to eliminate pollution from the source, make the whole synthesis process and production process environmentally friendly, and no longer use toxic and harmful substances and produce waste;
No more garbage disposal, which is a countermeasure to fundamentally 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.
