Diethylene Glycol (DEG) is a chemical compound of significant industrial importance, recognized for its versatile properties and wide-ranging applications. As a colorless, hygroscopic liquid with a slightly sweet taste, DEG serves critical functions across numerous sectors, from manufacturing polymers and resins to acting as a solvent and desiccant. For R&D scientists and procurement professionals, a thorough understanding of DEG’s characteristics and applications is key to leveraging its potential effectively.

Chemical and Physical Properties of DEG
Diethylene Glycol, with the chemical formula C4H10O3 and CAS number 111-46-6, is a dimer of ethylene glycol linked by an ether bond. Its molecular structure confers excellent solubility in water, alcohol, and ether, alongside a high boiling point (approximately 245°C) and low volatility. These attributes make it a stable and effective component in many chemical formulations. Its hygroscopic nature means it readily absorbs moisture from the air, a property that is harnessed in applications like gas dehydration.

Major Industrial Applications of Diethylene Glycol
DEG's versatility translates into a broad spectrum of industrial uses:

  • Plasticizers: DEG is a crucial intermediate in the synthesis of plasticizers, essential additives that enhance the flexibility and processability of polymers like PVC.
  • Solvents: It functions as a powerful solvent for resins, dyes, oils, and nitrocellulose, finding applications in paints, inks, coatings, and adhesives.
  • Chemical Intermediates: DEG is a key precursor in the production of unsaturated polyester resins (UPR) and polyurethanes, materials vital for composites, foams, and elastomers.
  • Gas Dehydration: In the petrochemical industry, it is used as a desiccant to remove water vapor from natural gas streams, preventing hydrate formation.
  • Humectants: Its ability to retain moisture makes it useful as a humectant in various industrial products.

Procuring High-Quality Diethylene Glycol
For manufacturers and researchers, securing a reliable supply of high-purity Diethylene Glycol is essential. Purity levels, often specified at 99.9%, are critical for ensuring optimal performance and preventing undesired reactions in sensitive applications. When looking to buy Diethylene Glycol, it is recommended to source from a reputable Diethylene Glycol manufacturer or a trusted CAS 111-46-6 chemical supplier. Such suppliers can guarantee product quality, provide Certificates of Analysis, and offer consistent availability.

Partnering with a Reliable Supplier
Many industries rely on a steady supply of DEG, making the choice of supplier a strategic one. A dependable Diethylene Glycol supplier in China or globally can offer competitive Diethylene Glycol price per ton for bulk orders and ensure timely delivery.
