1. Product Definition

High-Purity Solid Sodium Ethoxide is an inorganic compound with the chemical formula C₂H₅ONa. It presents as a white or slightly yellowish free-flowing powder. The term "high-purity" signifies a product with an exceptionally high active content (typically ≥98.5%) and critically low levels of impurities, such as free alkali (often measured as NaOH) and heavy metals.

This material is a powerful alkali and a cornerstone catalyst in modern organic synthesis, renowned for its superior performance over standard-grade alternatives.

2. Key Characteristics and Advantages

Our High-Purity Solid Sodium Ethoxide, produced via the advanced Sodium Metal Process, offers distinct advantages:

• Exceptional Purity (>98.5%): High active content ensures predictable stoichiometry and reaction outcomes, reducing side reactions and by-products.

• Low Free Alkali (Low NaOH): This is a critical quality indicator. Minimizing free sodium hydroxide prevents unwanted saponification and hydrolysis side reactions, which is vital for achieving high yields in sensitive syntheses, especially in the pharmaceutical industry.

• Enhanced Reactivity: As a strong base, it efficiently drives reactions like condensation, esterification, and alkoxylation with high speed and efficacy.

• Excellent Stability: Properly packaged and stored under moisture-free conditions, it maintains its potency and free-flowing physical properties over time.

• Free-Flowing Physical Form: Its powder form is engineered to facilitate accurate and safe handling, weighing, and dosing in industrial settings.

3. Manufacturing Process: The Sodium Method

The superior quality of our product is a direct result of the Sodium Method (or Sodium Process). This synthesis involves the direct reaction of high-purity metallic sodium with absolute (water-free) ethanol:

2 C₂H₅OH + 2Na → 2C₂H₅ONa + H₂↑

This process, followed by precise purification and drying steps, allows for meticulous control over the final product's composition, enabling the consistent production of a high-purity, low-impurity material that other methods cannot reliably match.

4. Applications

High-Purity Solid Sodium Ethoxide is an indispensable catalyst and reagent across several advanced industries:

• Pharmaceutical Industry: Widely used as a catalyst in the synthesis of Active Pharmaceutical Ingredients (APIs), including antibiotics, antidepressants, and other complex organic molecules. Its low impurity profile is essential for meeting stringent pharmacopoeia standards.

• Agrochemical Synthesis: Crucial for the production of pesticides, herbicides, and insecticides, where it facilitates key condensation and ring-closure reactions.

• Biodiesel Production: Serves as an efficient catalyst for the transesterification of vegetable oils or animal fats into biodiesel (fatty acid methyl esters) and glycerol.

• Fine Chemicals and Fragrances: Used in the synthesis of flavors, fragrances, and other specialty chemicals where high selectivity and yield are required.

• Organic Synthesis: A fundamental reagent for Claisen condensations, Williamson ether synthesis, and dehydrohalogenation reactions.

5. Why Choose Our High-Purity Solid Sodium Ethoxide?

• Increased Yield: Minimized impurities lead to fewer side reactions, directly boosting the yield of the target product.

• Superior Product Quality: Results in final products with better color, clarity, and purity.

• Process Efficiency: High reactivity can shorten reaction times and lower required reaction temperatures.
