Available in forms like caustic soda flakes, caustic soda liquid, and anhydrous grades, its versatility drives efficiency across diverse sectors.

This guide provides a comprehensive overview of caustic soda’s properties, production, applications, and benefits, offering valuable insights for businesses and individuals. Learn how high-quality sodium hydroxide from trusted suppliers like ZÜMRÜT International Kimya Co. can elevate your processes with safety and performance.

What is Caustic Soda?

Caustic soda, or sodium hydroxide (NaOH), is an inorganic compound renowned for its ability to neutralize acids, dissolve organic materials, and adjust pH levels. Produced through the chlor-alkali process, which electrolyzes sodium chloride (salt) solution, caustic soda is a key ingredient in chemical manufacturing, water treatment, food processing, and more. Its availability in various forms—flakes, liquid, and anhydrous—caters to specific industrial needs.

Key Features of Caustic Soda

  • Reactivity: Reacts vigorously with water, acids, and metals like aluminum, generating heat.

  • Versatility: Supports applications from heavy industry to household products.

  • Forms: Tailored as flakes, liquid solutions, or anhydrous powder for precise use.

Properties of Caustic Soda Flakes and Liquid

Caustic soda is available in two primary forms: flakes and liquid, each with distinct properties suited to specific applications.

Caustic Soda Flakes

  • Appearance: White, crystalline, solid flakes.

  • Purity: 98–99%.

  • Hygroscopic: Absorbs moisture from the air, requiring airtight storage.

  • Solubility: Highly soluble in water, releasing heat (exothermic reaction).

  • Melting Point: ~318°C (604°F).

  • Density: ~2.13 g/cm³.

  • Storage: Store in sealed containers to prevent clumping.

  • Reactivity: Reacts vigorously with water, acids, and metals, requiring careful handling.

Caustic Soda Liquid

  • Appearance: Clear, colorless solution, typically 30–50% concentration.

  • Density: ~1.33 g/cm³ for a 50% solution.

  • pH: Highly alkaline, pH 13–14.

  • Viscosity: Low, increasing with concentration.

  • Boiling Point: ~145°C for a 50% solution.

  • Freezing Point: -12°C to 12°C, depending on concentration.

  • Storage: Requires corrosion-resistant containers (e.g., polyethylene).

  • Reactivity: Highly reactive with acids and organic compounds, necessitating safety precautions.

How is Caustic Soda Produced?

Caustic soda is manufactured via the chlor-alkali process, an efficient electrolysis method. The process involves:

  1. Brine Preparation: Dissolving sodium chloride (NaCl) in water to form a brine solution.

  2. Electrolysis: Passing the brine through diaphragm or membrane cells to separate components.

  3. Chemical Reactions:

    • Sodium ions at the cathode combine with water to form sodium hydroxide (NaOH).

    • Chlorine gas (Cl₂) is released at the anode.

    • Hydrogen gas (H₂) is liberated at the cathode.

This method ensures high-purity caustic soda for industrial, food-grade, and pharmaceutical applications.

Grades of Caustic Soda

Caustic soda is available in multiple grades, each tailored to specific purity and application requirements.

1. Technical Grade

  • Purity: 95–98%.

  • Benefits: Safe for food contact, meeting stringent health standards.

3. Pharmaceutical Grade

  • Purity: >99.5%.

  • Applications: Drug synthesis (e.g., pain relievers, anticoagulants).

  • Benefits: Ensures precision and safety in medical applications.

4. Industrial Grade

  • Concentration: 50–75%.

  • Applications: Textile manufacturing, paper production, chemical processes.

  • Benefits: Suitable for heavy-duty tasks requiring moderate purity.

5. Anhydrous Grade

  • Purity: Nearly 100%, water-free.

  • Applications: Polymer production, fine chemical synthesis.

  • Benefits: Eliminates moisture interference in sensitive processes.
