For any industry relying on Epichlorohydrin (CAS: 106-89-8), understanding its manufacturing process and the stringent quality control measures employed is crucial. As a leading Epichlorohydrin manufacturer in China, we prioritize efficient synthesis and unwavering quality to meet the demanding specifications of our global clientele. This insight into our production practices aims to assure buyers of the reliability and performance of our product.

The most prevalent commercial method for producing Epichlorohydrin involves a two-step process starting with propylene. First, propylene undergoes chlorination at high temperatures to produce allyl chloride. Subsequently, allyl chloride is reacted with hypochlorous acid to form glycerol dichlorohydrin, followed by dehydrochlorination with a base, typically calcium hydroxide or sodium hydroxide, to yield Epichlorohydrin. This method is favored for its efficiency and yield in producing high-purity Epichlorohydrin.

Alternative synthesis routes also exist, such as the direct epoxidation of allyl chloride with peroxy acids or hydrogen peroxide under specific catalytic conditions. However, the allyl chloride route remains the most economically viable and widely adopted method for large-scale industrial production.

Quality control is an integral part of Epichlorohydrin manufacturing. From raw material inspection to final product analysis, every stage is meticulously monitored. Key quality parameters checked include:

  • Purity (Assay): Typically determined by Gas Chromatography (GC), ensuring it meets the specified percentage, often ≥99.5%.
  • Appearance: Visual inspection to confirm it is a clear, colorless oily liquid.
  • Moisture Content: Minimized to prevent unwanted side reactions.
  • Acidity: Measured to ensure stability and prevent corrosion.
  • Specific Impurities: Monitoring for critical by-products that could affect downstream applications.

Reputable manufacturers provide a Certificate of Analysis (CoA) with each batch, detailing these quality parameters. This document is vital for buyers to verify that the supplied Epichlorohydrin meets their specific application requirements, whether for epoxy resins, solvents, or other chemical syntheses.

When you choose to buy Epichlorohydrin from a trusted Epichlorohydrin supplier, you are investing in a product that has undergone rigorous testing and validation. We ensure that our manufacturing processes are optimized for both efficiency and environmental compliance, providing a stable and high-quality supply. Understanding the manufacturing journey from propylene to the final Epichlorohydrin product reinforces the value proposition for our customers.
