How Pure Melamine Powder is Produced: A Step-by-Step Guide‌

The industrial production of pure melamine powder involves advanced chemical synthesis and refining techniques. Below is a simplified breakdown of the process:

‌1. Raw Material Preparation‌

‌Primary Feedstock‌: Urea (CAS 57-13-6) is the primary raw material.

‌Pre-Treatment‌: Urea is purified to remove contaminants (e.g., biuret, ammonia) to ensure high-purity input for synthesis.

‌2. Synthesis Reaction‌

Melamine is synthesized through one of two main methods:

‌a. High-Pressure Non-Catalytic Process‌

‌Reaction‌: Urea is decomposed under high temperature (380–450°C) and pressure (8–10 MPa) in a molten state.

‌Chemical Equation‌:

6 , text{NH}_2text{CONH}_2 , (text{urea}) rightarrow text{C}_3text{H}_6text{N}_6 , (text{melamine}) + 6 , text{NH}_3 + 3 , text{CO}_26NH

CONH

(urea)→C

(melamine)+6NH

+3CO

‌Catalyst-Free‌: This method avoids catalysts, simplifying post-reaction purification.

‌b. Low-Pressure Catalytic Process‌

‌Catalyst‌: Aluminum oxide (Al₂O₃) or silica gel is used.

‌Conditions‌: Lower temperature (350–400°C) and atmospheric pressure.

‌3. Gas-Phase Purification‌

The reaction produces a gas mixture (melamine vapor, ammonia, CO₂).

‌Cooling & Crystallization‌: Melamine vapor is rapidly cooled to form solid crystals.

‌4. Washing and Refining‌

‌Centrifugation‌: Crude melamine is separated from residual gases and unreacted urea.

‌Acid Washing‌: Diluted sulfuric acid or water removes impurities (e.g., cyanuric acid, ammeline).

‌Recrystallization‌: Further purification ensures ≥99% purity.

‌5. Drying and Milling‌

‌Drying‌: Moisture is removed using rotary dryers or fluidized bed dryers.

‌Particle Size Control‌: The dried product is milled into fine, uniform powder (typical particle size: 100–500 µm).

‌6. Quality Control‌

‌Purity Testing‌: HPLC (High-Performance Liquid Chromatography) or GC (Gas Chromatography) verifies ≥99% purity.

‌Physical Properties‌: Color (pure white), solubility, and thermal stability are tested.

‌7. Packaging and Storage‌

‌Moisture-Proof Packaging‌: Sealed in multi-layer polyethylene or aluminum bags.

‌Storage Conditions‌: Kept in dry, cool environments away from UV light.

‌Key Environmental and Safety Measures‌

‌Ammonia Recovery‌: NH₃ byproduct is captured and reused in urea production.

‌Wastewater Treatment‌: Acidic washwater is neutralized before disposal.

‌Dust Control‌: Closed systems prevent airborne melamine particles.

‌Global Production Standards‌

Leading manufacturers (e.g., in China, Europe) adhere to ISO 9001 and REACH regulations.

Industrial-grade melamine typically meets ASTM D 3638 specifications.

This streamlined process ensures the production of high-purity melamine powder for applications in plastics, coatings, flame retardants, and adhesives. Let me know if you need deeper technical details!
