Fluorine, the Chemistry Enfant

The matter in the universe is composed of various chemical elements, among which there is a unique and magical element, that is fluorine. The chemical element fluorine has a bad reputation, but it has great merits.The single substance of fluorine is a highly toxic gas with strong corrosiveness, and some fluorine chemical raw materials such as tetrafluoroethylene are extremely active. The single substance of fluorine is F2, which is a light yellow and highly toxic gas. Fluorine gas is highly corrosive and has extremely active chemical properties. It is one of the most oxidizing substances and can even react with some inert gases under certain conditions. Fluorine is a key element in special plastics, rubber and refrigerants (chlorofluorocarbons). In nature, fluorine mainly exists in fluorite (CaF2), cryolite (Na3[AlF6]) and fluoroapatite (Ca10(PO4)6F2).Organic fluoride has a mild and unique side: it is as stable as other organic compounds and can greatly improve the biochemical and physicochemical properties of medicine and pesticide molecules. The toothpaste, refrigerants, non-stick pan coatings, spacecraft sealing materials and some new drugs we are familiar with all contain fluorine.In the international fluorine chemistry scientific community, there are two words used to summarize the importance of fluorine. The first is unique. It is the most subversive element. Why can "most" be used to describe a chemical element? This is because fluorine has a high electronegativity and very extreme chemical properties. This makes many fluorine-containing raw materials very active, but fluorine-containing products are very stable - when active fluorine-containing raw materials undergo chemical reactions, they will release a lot of energy, but the fluorine-containing products obtained after the energy is released are particularly stable. This process is a bit like popcorn, which has experienced "explosion" and then precipitated. Fluorine can also form the strongest chemical bond with carbon atoms. This property makes fluorine-containing materials very stable. For example, the plastic mesh Teflon, that is, polytetrafluoroethylene, is one of the most stable materials.The second word to describe fluorine is useful. 20%-25% of newly registered drugs worldwide contain fluorine atoms. Some patients also use 18F-FDG, or fluorodeoxyglucose, when undergoing PET-CT examinations. Fluorine-containing liquid crystal materials are used in the display screens of electronic devices such as mobile phones and computers that people use in their daily lives.The application of fluorine-containing materials in the defense field is also very extensive. In the aerospace field, gyro oil, high and low temperature lubricating oil, etc. are all fluorine-containing materials. Among the cutting-edge defense materials required for atomic bombs, fluorine-containing materials also occupy an important place. In addition, fluoride is necessary for the human body within a certain range. The right amount of fluoride promotes the growth and formation of teeth and bones, and is beneficial to the healing and calcification of fractures. Insufficient fluoride will lead to rickets, osteoporosis, dental caries and other diseases.Reasonable intake of fluoride can ensure the body's normal calcium and phosphorus metabolism and promote the normal growth and development of bones. Under the action of fluoride, hydroxyapatite can be converted into hard-surfaced fluorapatite, enhancing bone mineralization. After fluoride is absorbed by hydroxyapatite in tooth enamel, it produces acid-resistant fluorapatite on the tooth surface, which can prevent tooth decay.The safe range of fluoride for the human body is very narrow, which makes the balance between human activities and fluoride easily destroyed. When fluoride is excessive, deficient or unbalanced, it will affect the metabolism and immune regulation of the human body.When we look at the fluorine element, from research to application, it is always accompanied by sacrifice and harm. But is fluorine really harmful to humans? In fact, humans now have a more comprehensive understanding of fluorine, and fluorine is more scientifically used in various fields such as pesticides, medicine, materials, atomic energy, aerospace, etc. While using fluorine to improve our lives, we are also working hard to make it live in harmony with humans and the environment.2024-09-13

Fluorine Chemical Industry-Deeply Cultivated in the Industry, Entering into Life

1. Fluorine Chemical IndustryFluorine chemical industry is a sub-industry of the chemical industry. Its products have high performance and high added value, and it is known as the golden industry. Fluorine chemical industry is mainly divided into two major industries: inorganic fluorine chemical industry and organic fluorine chemical industry.Inorganic fluorine chemical products are important raw materials and auxiliary materials for industries such as machinery, electronics, and metallurgy, while organic fluorine chemical products are widely used in military, chemical, and machinery fields due to their excellent properties such as resistance to chemicals, high and low temperature resistance, aging resistance, low friction, and insulation.2. The fluorine chemical industry has become one of the fastest growing industries in the chemical industry.The emergence and development of fluorine chemical industry is closely related to human's understanding and application of fluorine element and its compounds.In nature, fluorine is widely distributed in the form of simple substance or compound, the most important of which are hydrogen fluoride (HF) and silicon tetrafluoride (SiF4). With the advancement of science and technology and the need for industrial production, humans began to mine and utilize fluorine and its compounds, and gradually developed two major industries: inorganic fluorine chemical industry and organic fluorine chemical industry.Inorganic fluorine chemical industry originated in the early 20th century, when fluorite (CaF2) was mainly used to produce hydrofluoric acid (HF), and then other fluorides. Later, with the advancement of technology and the expansion of application fields, inorganic fluorine chemical industry gradually developed into an industry with a complete range of categories and a wide variety of products.The development of organic fluorine chemicals began after World War II. With the advancement of technology and the increase in demand, it gradually developed into an industry with chlorofluorocarbons (CFCs) and chlorofluorocarbons (HCFCs) as its main products.Since the 1980s, with the increasing attention paid to environmental issues and the improvement of environmental awareness, organic fluorine chemicals have gradually developed towards high efficiency, environmental protection and high performance, and inorganic fluorine chemicals have also developed towards deep processing, refinement and high-end development, continuously launching new products and new application areas.3. Fluorine chemical products have many applications in daily life. The following are some common fluorine chemical products:1. Refrigerant: Refrigerant is a traditional product in the fluorine chemical industry, including four generations of refrigerant products, namely CFCs, HCFCs, HFCs and HFOs. Among them, CFCs have been eliminated, and the global market currently mainly uses second, third and fourth generation refrigerants, such as Freon (chlorofluorocarbons).2. Fluoride toothpaste: In order to prevent tooth decay, we usually use fluoride toothpaste. These toothpastes often contain trace amounts of sodium fluoride or other fluorides.3. Teflon: Teflon (polytetrafluoroethylene) is a polymer material, commonly used as a coating for non-stick pans.4. Fluorinated drugs: Some drugs use fluorine atoms to improve their properties, such as biological activity, prolonged efficacy, etc. For example, flunarizine has a longer-lasting efficacy and fewer side effects than cinnarizine.5. Artificial blood: Artificial blood products such as perfluorodecalin are also one of the applications of fluorine chemical products.6. Fire extinguishing agents and pesticides: Certain fire extinguishing agents (such as hexafluoropropane) and fluorine-containing pesticides are also applications of fluorine chemical products.In addition, fine chemicals such as fluorinated organic intermediates and fluorinated lithium salt electrolytes (such as lithium hexafluorophosphate LiPF6 and lithium bis(fluorosulfonyl)imide LiFSI) are also widely used in daily life, such as in batteries and electronic devices.2024-08-16
