There are those in green chemistry in everyday life

For example, all the products produced by the dry distillation of coal are completely utilized.

High technical content. Economy. Environmental protection.

Green chemistry involves organic synthesis, catalysis, biochemistry, analytical chemistry, etc. Green Chemistry advocates the use and production of chemical technologies and methods to reduce or stop using and producing raw materials, catalysts, solvents and reagents, products and by-products that are harmful to human health, community safety and the ecological environment.

But with the development of the discipline. It itself is gradually tending to practical application in the continuous development and change, and its development is closely related to chemistry. The ideal of green chemistry is to eliminate pollution at the source of production, make the entire synthesis and production process environmentally friendly, stop using toxic and hazardous substances, generate waste, and dispose of waste.

This is a fundamental measure to eliminate pollution. Thanks to the scientific means employed to prevent the beginning of pollution, the process and the end point are zero emission or zero pollution.

Green chemistry, also known as environmentally benign chemistry, environmentally friendly chemistry, and clean chemistry, is the design of chemicals and processes that reduce or eliminate the use and generation of hazardous substances. Green chemistry involves organic synthesis, catalysis, biochemistry, analytical chemistry and other disciplines, with a wide range of contents. Green chemistry advocates the use of chemical technologies and methods to reduce or stop the use and production of raw materials, catalysts, solvents and reagents, products, and by-products that are harmful to human health, community safety, and the ecological environment.

Green chemistry advocates the use of chemical technologies and methods to reduce or stop the use and production of raw materials, catalysts, solvents and reagents, products, and by-products that are harmful to human health, community safety, and the ecological environment. The definition of green chemistry is constantly evolving and changing.

When it first appeared, it represented more of an idea, a desire. However, with the development of the discipline, it gradually tends to be applied in the continuous development and change, and its development is closely related to chemistry. In 1992, Professor Pt Anastas, an advocate of green chemistry and former director of the Green Chemistry Institute in the United States, and a professor at Yale University, proposed the definition of "green chemistry".

chemical products and processes that reduce or eliminate the use and generation of hazardous substancese.i.e. "the design of chemicals and processes that reduce or eliminate the use and generation of hazardous substances". From this definition, green chemistry is based on chemistry, while its application and implementation are more like chemicals.

Green chemistry is getting more and more involved.

Green chemistry is not the same as pollution control chemistry. The object of pollution control chemistry research is the chemical technology and principle of remediation of the polluted environment, so that it can be restored to its pre-polluted appearance. The ideal of green chemistry is to eliminate pollution at the source of production, make the entire synthesis process and production process environmentally friendly, no longer use toxic and harmful substances, no longer produce waste, no longer dispose of waste, which is a fundamental countermeasure to eliminate pollution.

Thanks to the scientific approach to pollution prevention from the start, the process and the end are zero or zero pollution. Many countries in the world have taken "greening of chemistry" as one of the main directions of chemical progress in the new century.

Green chemistry has the following characteristics:

1.Reduce pollution: Green chemistry emphasizes the use of low-toxic, non-toxic, and renewable raw materials, and avoids the use of solvents, substrates and catalysts with poor environmental performance.

2.Energy and resource saving: Green Chemistry reduces energy and raw material consumption by controlling the reaction rate, designing a reasonable reaction process, and strengthening the utilization of waste.

3.Easy operation: Compared with traditional organic synthetic chemistry, green chemistry can make the operating conditions milder and easier to achieve automatic control in the reaction process, thereby greatly reducing the cost of track preparation and labor cost.

4.Increase the added value of products: Green chemistry products can be tested through bioactivity tests to prove that they pose less risk to humans and the environment, thereby gaining consumer trust and generating great economic potential.

In short, green chemistry is a chemical system that aims to reduce or eliminate harm to human health and the environment, while improving production efficiency and resource utilization. It is different from traditional organic synthesis chemistry in that it adopts new methods, processes, catalysts, reaction conditions, etc. It is a new chemical system that aims to reduce the harm to health and ecology while maximizing energy resources, increasing the efficiency of production and the added value of products.

Green chemistry will play an increasingly important role in sustainable development in the future.

1.Make full use of resources and energy, and use non-toxic and harmless raw materials;

2.Under non-toxic, harmless conditions.

to reduce the discharge of waste into the environment;

3.Improve the utilization rate of atoms, and strive to make all atoms as raw materials be absorbed by the product to achieve "zero emissions";

4.Produce environmentally friendly products that are conducive to environmental protection, community safety, and human health.

Scientific means of pollution prevention are used at the beginning, so that the process and end are zero emission or zero pollution. The atoms of the reactants are all converted into the desired end product.

1. The definition of green chemistry is: the use of chemical technologies, principles and methods to eliminate toxic and harmful chemicals to human health, safety and ecological environment, so it is also called environmentally friendly chemistry or clean chemistry.

2. One of the core contents is "atomic economy".

3. The second core content, five aspects.

The first is "reduction", that is, to reduce the emission of "three wastes";

The second is "reuse", such as catalysts and carriers in the chemical industry, which is the need to reduce costs and waste;

The third is "**", which can effectively achieve the requirements of "saving resources, reducing pollution, and reducing costs";

The fourth is "regeneration", that is, an effective way to turn waste into treasure, save resources and energy, and reduce pollution;

The fifth is "refusal", which refers to the refusal to use in the chemical process for some irreplaceable, regeneration, regeneration, and reusable, toxic and polluting raw materials, which is the most fundamental way to eliminate pollution.

Green chemistry is mainly evaluated from the safety of raw materials, the energy saving of the process, the economy of the reaction atoms and the environmental friendliness of the products. Atomic economics and the "5R" principle are at the heart of green chemistry. Atom economy refers to the full use of the individual atoms in the reactants, so as to make the best use of resources and prevent contamination.

The atom utilization rate is super ionized, and each raw material in the raw material can be maximized, so that it can be combined into the target product, the less waste produced by the reaction, and the less pollution caused to the environment, the 5 "R" principles of the green experiment should be followed in the experimental process, namely.

1. Reduction: Reduce the use of raw materials and reduce the generation and emission of experimental waste.

2. Reuse, recycling, reuse.

3. Recycling, to achieve the best utilization of resources, so as to achieve "saving resources, less pollution, and reducing costs".

4. Regeneration, recycling, turning waste into treasure, and reusing resources and energy are effective ways to reduce pollution.

5. Rejection, refuse to use toxic and harmful products, refuse to use some irreplaceable and irreplaceable, regenerative and reusable, toxic and polluting raw materials, which is the most fundamental way to eliminate pollution.

1. Atomic economy.

2. Reduction, that is, reducing the emission of "three wastes".

3. Reuse, such as catalysts and carriers in the chemical industry, which is the need to reduce costs and waste.

4. It can effectively realize the requirements of "saving resources, reducing pollution and reducing costs".

5. Regeneration, that is, an effective way to turn waste into treasure, save resources and energy, and reduce pollution.

6. Refusal refers to the refusal to use in the chemical process for some irreplaceable, regenerated and reused, toxic and polluting raw materials, which is the most fundamental way to eliminate pollution.

According to the definition of the American journal "Green Chemistry", green chemistry refers to the efficient use of (preferably renewable) raw materials, the elimination of waste and the avoidance of toxic and dangerous reagents and solvents in the manufacture and application of chemical products.

Technical principle: It can avoid burdening the environment and emitting harmful substances through the use of natural energy. We will develop manufacturing and storage technologies for photocatalysts and hydrogen energy using solar energy, and consider energy conservation, resource conservation, and waste reduction.

Green chemistry, also known as environmentally friendly chemistry, environmentally sound chemistry, and clean chemistry, is the use of chemical technologies and methods to reduce or eliminate the production and use of harmful substances.

Its core is to use chemical principles to reduce and eliminate the pollution of industrial production to the environment from the source, and convert all the atoms of the reactants into the desired final product.
