Overview
Industrial-grade sodium phenolate is a sodium salt of phenol, widely used as an intermediate in chemical synthesis. It is produced by the reaction of phenol with sodium hydroxide. The industrial-grade variant is typically less pure than pharmaceutical-grade but meets the requirements for bulk chemical applications. Its strong alkalinity and solubility make it valuable in various industrial processes. Sodium phenolate is essential in the production of dyes, pharmaceuticals, and resins. It acts as a precursor in synthesizing other phenolic compounds and is used in the manufacture of disinfectants and preservatives. Its industrial importance stems from its reactivity and versatility in chemical reactions.
Physical and Chemical Properties
Sodium phenolate appears as a white to light pink crystalline powder with a density of 1.22 g/cm³. It is highly soluble in water and alcohol, forming strongly alkaline solutions. The compound decomposes at temperatures above 300°C and is hygroscopic, meaning it absorbs moisture from the air. The chemical is strongly alkaline and reacts violently with acids, releasing phenol. It is corrosive to metals, skin, and eyes, requiring careful handling. Its reactivity makes it useful in organic synthesis, particularly in reactions requiring a strong base or nucleophile.
Main Applications
Sodium phenolate is primarily used as an intermediate in the production of pharmaceuticals, including aspirin and other salicylates. It is also a key component in dye manufacturing, where it helps form azo dyes and other colorants. In the resin industry, it serves as a catalyst or reactant in phenolic resin production. Additionally, sodium phenolate is employed in the synthesis of disinfectants and preservatives due to its antimicrobial properties. Its role in organic synthesis extends to the production of plasticizers, rubber chemicals, and other specialty chemicals. The compound's versatility makes it indispensable in multiple industrial sectors.
Safety and Storage
Sodium phenolate is corrosive and can cause severe burns to skin and eyes. Proper personal protective equipment (PPE), including gloves, goggles, and lab coats, must be worn when handling the chemical. Inhalation of dust or fumes should be avoided, and work areas must be well-ventilated. The compound should be stored in a cool, dry place, away from acids and oxidizing agents. Containers must be tightly sealed to prevent moisture absorption. Spills should be neutralized with a weak acid (e.g., vinegar) and cleaned up promptly. Emergency eyewash stations and showers should be accessible in areas where the chemical is used.
B2B Procurement Guide
When procuring industrial-grade sodium phenolate, buyers should verify the supplier's compliance with industry standards such as ISO or GMP. The purity level should meet the specific requirements of the intended application, typically ranging from 95% to 99% for industrial use. Bulk purchasing (e.g., tonnage quantities) often reduces costs, but storage conditions must be adequate to prevent degradation. Buyers should request material safety data sheets (MSDS) and certificates of analysis (CoA) to ensure quality and safety. Establishing long-term relationships with reputable suppliers can secure consistent quality and competitive pricing.
