Overview
Sodium phenolate is an organic sodium salt derived from phenol. It is widely used in industrial chemistry due to its reactivity as a strong base and its role as a precursor in synthetic processes. This compound is typically produced by the reaction of phenol with sodium hydroxide. Its hygroscopic nature requires careful handling and storage to prevent degradation and ensure consistent performance in applications.
Physical and Chemical Properties
Sodium phenolate appears as a white to light yellow crystalline powder. It is highly soluble in polar solvents like water and alcohols, which facilitates its use in liquid-phase reactions. As a strong base, it reacts vigorously with acids to regenerate phenol. Its hygroscopicity means it readily absorbs moisture from the air, which can affect its stability and handling. The compound decomposes upon heating, releasing toxic fumes of sodium oxides.
Main Applications
In the pharmaceutical industry, sodium phenolate serves as an intermediate for synthesizing drugs like aspirin and other salicylates. It is also used in the production of dyes, where it acts as a coupling agent. Another significant application is in resin manufacturing, particularly for phenolic resins used in adhesives and coatings. Additionally, its disinfectant properties make it valuable in sanitizing formulations, though this use is less common due to safety concerns.
Safety and Storage
Sodium phenolate is corrosive and can cause severe skin and eye damage. Proper personal protective equipment (PPE), including gloves and goggles, is essential when handling this chemical. Store it in airtight containers in a cool, dry place, away from acids and oxidizing agents. Spills should be neutralized with a weak acid (e.g., vinegar) and cleaned up promptly to prevent environmental contamination.
B2B Procurement Guide
When procuring sodium phenolate, prioritize suppliers with verified quality control processes. Key specifications include purity (≥98%), moisture content, and absence of heavy metals. Bulk purchases (drums or bags) typically offer cost advantages, but ensure packaging is moisture-proof. Request SDS and CoA documents to confirm compliance with industry standards like REACH or USP, depending on your application.
