[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods of sodium phenolate, is sodium phenolate toxic and harmful to human body

Phenol sodium salt properties

Sodium phenol (sodium Phenoxide), the chemical formula is C6H5ONa, is produced by the reaction of phenol (C6H5OH) with sodium hydroxide (NaOH). Phenol sodium salt is a white or light yellow solid with strong alkalinity. It is easily soluble in water and exhibits strong ionization ability in aqueous solution, generating phenol ions and sodium ions. The solubility of sodium phenolate in water increases with increasing temperature, which makes it widely adaptable in industrial applications. Phenol sodium salt has strong nucleophilicity, which makes it play an important role as an intermediate in organic synthesis.

Phenol sodium salt uses

Sodium phenolates have a wide range of uses in the chemical industry. It is an important intermediate in organic synthesis and is used in the synthesis of various phenolic derivatives, such as phenolic resins, dyes and drugs. Sodium phenolate is also used in pesticide production as an intermediate for some herbicides and fungicides. In the field of medicine, sodium phenolate is used to prepare some important drugs, such as antipyretic analgesics and antibacterial drugs. Its strong alkalinity and nucleophilicity make it have unique advantages in organic chemical reactions and can effectively promote the reaction process.

Upstream raw materials

The production of sodium phenolate mainly depends on two upstream feedstocks: phenol and sodium hydroxide. Phenol, chemical formula C6H5OH, is an important organic chemical raw material, widely used in the production of plastics, pharmaceuticals, fungicides and so on. There are two main methods for the preparation of phenol: from benzene and propylene in the petrochemical industry through the cumene process; from the phenol-chlorobenzene process in the coal chemical industry. Sodium hydroxide, caustic soda, is a basic chemical raw material, widely used in papermaking, textile, soap, synthetic detergent, petroleum refining and other industries. Sodium hydroxide is mainly obtained by electrolysis of saturated salt water.

Downstream Products

The downstream products of sodium phenolate mainly include phenolic resin, dyes, drugs, pesticides, etc. Phenolic resin is one of the earliest synthetic resins, widely used in the manufacture of heat-resistant, corrosion-resistant materials, such as electrical insulation materials, brake pads and so on. In terms of dyes, sodium phenolate is an important intermediate for the manufacture of certain azo dyes, which are widely used in the textile industry. On the pharmaceutical side, sodium phenolate is a precursor for some antibacterial and antipyretic analgesics. In pesticide production, sodium phenolate is an important intermediate of some herbicides and fungicides, which play an important role in agricultural production.

Phenol sodium salt production process

Phenol sodium salt is mainly produced by the reaction of phenol with sodium hydroxide. The specific steps are: dissolving phenol in an appropriate amount of water, then slowly adding sodium hydroxide solution, and controlling the reaction temperature and reaction time to ensure that the reaction is fully carried out. After completion of the reaction, the sodium phenolate salt was separated from the solution by cooling crystallization. To improve yield and purity, multiple crystallizations and filtrations may be performed. In the reaction process, the reaction conditions need to be strictly controlled to avoid the occurrence of side reactions, so as to ensure the quality and yield of the product.

Phenol sodium salt storage method

Phenol sodium salt has strong alkalinity and strong hygroscopicity, and is easy to react with carbon dioxide and moisture in the air. Therefore, the storage of phenolsodium salt requires special attention. Sodium phenolates should be stored in a sealed container, avoid contact with air. Storage environment should be dry, well ventilated, avoid humidity and high temperature. Sodium phenolates should be kept away from acidic substances and flammable substances to prevent chemical reactions or fires. During transportation, moisture-proof packaging should be used, and protective measures should be taken to avoid contact with moisture and vibration.

Phenol sodium salt safety

Phenol sodium salt has strong alkaline, has a strong stimulating effect on the skin and mucous membrane, after contact will cause burns. Therefore, in the handling and use of sodium phenolate, strict protective measures need to be taken. Operators should wear protective clothing, gloves, goggles, etc. to avoid skin and eye contact with sodium phenolate. If accidentally contact, should immediately rinse with plenty of water, and timely medical treatment. Because sodium phenol has certain harm to the environment, it should be carried out in accordance with hazardous waste treatment standards to avoid environmental pollution.

Phenol Sodium Salt Market Prospects

With the development of the chemical industry, the market demand for sodium phenol has shown a steady growth trend. Especially in the fields of organic synthesis, medicine and pesticide, the demand of sodium phenol as an important intermediate is increasing. The continuous strengthening of environmental protection policies has also promoted the development and application of the green production process of sodium phenol. It is expected that in the future, the sodium phenol salt market will continue to grow, and the application field of the product will continue to expand.

Summary

As an important chemical intermediate, sodium phenolate has unique physical and chemical properties and a wide range of applications. From the acquisition of upstream raw materials, to the optimization of production processes, to the development of downstream products, sodium phenolates play an important role in the chemical industry chain. With the increase of market demand and the progress of technology, the application prospect of sodium phenol will be more broad. In the process of production and use, strict safety management and environmental protection measures are also the key to ensure its sustainable development.
