What are the green chemistry products and what is green chemistry?

Green Chemistry. There are many products, such as low or mercury-free green batteries, green pesticides, and degradable plastics.

Green cars and much more.

Green chemical products are: chemical products that are harmless to humans and the environment are called green chemical products. Two characteristics of green chemical products:

1. The product itself will not cause environmental pollution and health problems, including no damage to wildlife, beneficial insects or plants;

2. When the product is used, it should be recyclable or easily degraded into harmless substances in the environment.

The main features of green chemistry are:

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

2 Reactions are carried out 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 products to achieve "zero emissions";

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

Green chemistry is also known as green technology, environmentally sound chemistry, environmentally friendly chemistry, and clean chemistry. Green chemistry is the use of chemistry and other technologies and methods to reduce or eliminate the use and production of raw materials, catalysts, solvents, reagents, products, by-products, etc., which are harmful to human health, community safety, and the ecological environment.

The products obtained by the above methods are called green chemical products.

Example: CO2 to make degradable plastics spinosasad Polymer synthesis using microorganisms.

There are many green chemical products, such as low- or mercury-free green batteries, green pesticides, degradable plastics, green cars, and more. Green chemical products are chemical products that are harmless to humans and the environment.

The main features of green chemistry are:

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

2. Carry out the reaction base under non-toxic and harmless conditions to reduce the discharge of waste to the environment;

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

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

Green Chemistry Green chemistry, also known as "environmentally sound chemistry", "environmentally friendly chemistry", and "clean chemistry", green chemistry has only been produced and developed in the past ten years, and it is a "new chemical baby". It covers a wide range of disciplines such as organic synthesis, catalysis, biochemistry, analytical chemistry, etc. The biggest feature of green chemistry is that it adopts scientific means to prevent pollution at the beginning, so the process and the end are zero emission 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.

One of the core elements of green chemistry is "atom economy", that is, the full use of the individual atoms in the reactants, so as to make the best use of resources and prevent pollution. The concept of atomic economy was put forward in 1991 by the famous American organic chemist Trost (for which he won the academic award of the first green chemistry challenge award in 1998), the atomic economy of the reaction is measured by the atomic utilization rate, and each atom of the raw material molecule should be maximized for efficient organic synthesis, so that it can be combined into the target molecule to achieve zero emission. Green organic synthesis should be atom-economical.

The higher the atom utilization, the less waste the reaction will produce and the less pollution it will cause to the environment.

The second core content of green chemistry is mainly reflected in the five "R": the first is reduction, that is, to reduce the emission of "three wastes"; The second is reuse - "reuse", such as catalysts and carriers in the chemical industry, which is the need to reduce costs and waste; The third is recycling - "**", which can effectively achieve the requirements of "saving resources, reducing pollution and reducing costs"; The fourth is regeneration - "regeneration", that is, an effective way to turn waste into treasure, save resources and energy, and reduce pollution; The fifth is rejection - "refusal", which refers to the refusal to use in the chemical process for some irreplaceable, regeneration, regenerative and reusable, toxic and polluting raw materials, which is the most fundamental way to eliminate pollution.

The definition of green chemistry is to use 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. In fact, green chemistry is not a completely new science.

Green chemistry not only has significant social, environmental and economic benefits, but also shows that the negative effects of chemistry can be avoided and shows human agency. Green chemistry embodies the interconnection and interaction between chemical science, technology and society, and is the product of the high development of chemical science and the role of society in the development of chemical science, which is the arrival of a new stage for chemistry itself. As a generation in the new century, we must not only have the ability to develop new and more environmentally friendly chemistry to prevent chemical pollution; Moreover, it is necessary for the younger generation to understand green chemistry, accept green chemistry, and make due contributions to green chemistry. 】

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, surplus products, and by-products that are harmful to human health, community safety, and the ecological environment.

The English name of green chemistry is green chemistry, also known as environmentally friendly chemistry or environmentally friendly chemistry. Chemicals and processes designed to reduce or eliminate the use and production of hazardous substances are called green chemistry.

The ideal of green chemistry is to no longer use toxic and harmful substances, no longer produce waste, no longer dispose of waste, this is a chemistry that reduces or eliminates pollution from the source. Green chemistry is the use of chemical principles to reduce and eliminate the pollution caused by industrial production to the environment from the source. It is also known as "environmentally sound chemistry", "environmentally friendly chemistry", and "clean chemistry".

Characteristics of green chemistry research1. Use non-toxic and harmless raw materials;

2. It is carried out under non-toxic and harmless conditions (including catalysts and solvents);

3. The product should be environmentally friendly;

5. It has "atomic economy", that is, the reaction has high selectivity, few by-products, and even achieves "zero emission". In addition, it should meet the traditional standard of "good quality and low price".
