[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods of phorone, why is isophorone called 783

Properties of

Phorone (also known as acetol or dimethyl ketol), the chemical name is 2-methyl-3-buten-2-ol, and the chemical formula is C5H10O. Phorone is a colorless liquid with a strong aromatic odor. Its physical properties include a melting point of -60°C, a boiling point of 102-104°C, and a density of about 0.85g/cm³. Phorone is a flammable substance with a flash point of about 20°C. Because of its structure containing hydroxyl and double bonds, phorone in the chemical properties of a certain activity, can react with a variety of reagents, such as oxidation, reduction, addition and polymerization.

The use of

Phorone is widely used in many fields such as chemical industry, medicine, spices and pesticides. In the field of chemical industry, phorone can be used as an intermediate in organic synthesis and participate in the synthesis of a variety of compounds. For example, it can be used to synthesize methacrolein, methyl methacrylate, etc. In the field of medicine, phorone is used as a solvent and reaction medium for the synthesis of antibiotics, vitamins and other drugs. In the perfume industry, because of its aromatic odor, is used as a perfume raw material or additive. In the pesticide industry, phorone is used as a synthetic intermediate for certain pesticides, particularly in the production of herbicides and insecticides.

Forone upstream and downstream raw materials

The upstream raw materials of phorone mainly include acetone and butene. Acetone can be formed by hydrogenation or reduction reaction, while butene is formed by oxidation reaction. In industrial production, the common production method includes the condensation reaction of acetone and butene in the presence of a catalyst, which has the advantages of high efficiency and low cost. The downstream products of phorone mainly include a variety of organic compounds, such as methacrylic acid, methacrolein, etc., these compounds are widely used in plastics, rubber, coatings and other industries.

Phorone storage method

Since phorone is a flammable liquid, its storage requires special attention to fire and explosion prevention measures. Phorone should be stored in a cool, dry, well-ventilated warehouse, away from fire, heat and oxidizing agents. Storage containers shall be of well-sealed metal or glass and shall be clearly marked as flammable. The warehouse shall be equipped with fire fighting equipment, such as dry powder fire extinguishers, carbon dioxide fire extinguishers, etc., so that they can be extinguished in time in case of fire. Personnel should wear protective equipment such as protective gloves, goggles and protective clothing to avoid direct contact when handling forone.

Safe handling of

Safety procedures must be strictly observed during the use and handling of phorone. Due to the volatile and flammable nature of phorone, a well-ventilated environment should be maintained during use to avoid inhalation of its vapors. In the event of a spurone leak, personnel in the leak area should be evacuated quickly and all sources of fire should be cut off. A small amount of leakage can be absorbed by inert adsorption materials such as sand or diatomite, and then collected in a closed container for treatment; when a large amount of leakage, a dam should be constructed to prevent diffusion, and an explosion-proof pump should be used to transfer to a special container for treatment.

Environmental Impacts and Regulations

Phorone is harmful to the environment, especially in water and soil persistence and toxicity to organisms. Strict pollution control measures must be taken during the production, use and disposal of forone to avoid its discharge into the environment. Many countries have established corresponding regulations and standards for the use and discharge of phorone. For example, the U.S. Environmental Protection Agency (EPA) has strict limits on industrial emissions of phorone, and China also has clear regulations on its emission concentration. The disposal of waste phorone must be carried out in accordance with hazardous waste disposal standards to ensure that the impact on the environment is minimized.

Market Prospects and Trends

With the continuous development of chemical, pharmaceutical and agricultural industries, the market demand for phorone is also increasing year by year. Especially in the context of environmental protection and sustainable development, as an important organic synthesis intermediate, the green production process and application of phorone have attracted much attention. In the future, with the progress of technology and the change of market demand, the production process of forone will be more efficient and environmentally friendly, and its application field will be further expanded. Relevant enterprises will pay more attention to environmental protection and safety in the R & D and production of forone to cope with increasingly stringent environmental regulations and market competition.

Conclusion

As an important chemical raw material, phorone has broad application prospects and market demand. Its nature determines its important position in many fields, but it also puts forward high requirements for its storage, processing and environmental management. With the continuous progress of technology and the enhancement of environmental awareness, the green production and application of forone will become an important development direction in the future. By strengthening the safety management and environmental protection measures, we can effectively reduce the harm to the environment and human body, and promote the sustainable development of the chemical industry.
