No.CAS:111-46-6

Diethylene glycol (DEG) is a byproduct of ethylene glycol production and an important versatile diol. It is primarily used as a desiccant for natural gas dehydration, a chain transfer agent or chain extender in polyester/polyurethane resin production, a solvent for unsaturated polyester resins, and also as a textile dyeing auxiliary, lubricant viscosity modifier, and component in certain specialty antifreeze formulations.

Description

Diethylene glycol (abbreviated as DEG, CAS No.: 111-46-6) is a dimeric ether-diol formed by the dehydration condensation of two molecules of ethylene glycol. Its molecular structure contains two hydroxyl groups and one ether linkage, conferring hygroscopicity, water solubility, and some freezing point depression ability similar to ethylene glycol, but with significantly higher toxicity. Its main industrial applications include:
1. Natural Gas and Gas Processing: Its high hygroscopicity makes it an effective desiccant for dehydrating natural gas, air, and other industrial gases (triethylene glycol TEG is more common, but DEG is also applicable).
2. Resin and Polymer Industry: Used as a chain transfer agent or chain extender in polyester (PET, PBT) and polyurethane production to regulate molecular weight. It is also a common active diluent and solvent for unsaturated polyester resins (used in fiberglass).
3. Textile and Dyeing: Employed as a dye solvent and humectant in fabric finishing agents, helping to improve dye dispersion and fabric hand.
4. Functional Fluids and Additives: Used as a viscosity modifier and antifreeze in lubricants, hydraulic oils, and brake fluids; as a solvent and humectant in printing inks; and as a component in certain low-toxicity antifreeze formulations (e.g., for solar energy systems).
5. Other Uses: Used in the production of chemicals like morpholine, and as a component in adhesives and sealants.
Our product, manufactured in Shandong, China, is primarily a byproduct from the hydration of ethylene oxide to produce ethylene glycol, refined via distillation to achieve a purity of ≥99.0%. This product is toxic (LD₅₀ oral rat approx. 12-20 g/kg). Ingestion may cause severe health issues such as kidney failure. It is strictly forbidden for use in pharmaceuticals, food, cosmetics, or any end products that may come into human contact. Protective gloves and goggles must be worn during handling to avoid contact with skin and eyes.
