Triethylene Glycol Colourless Liquid TEG CAS 112-27-6

 

 

Description:
Triethylene Glycol (TEG) is a viscous liquid that belongs to the class of glycols. It is composed of three ethylene glycol units linked together, which gives it its name.

Specification:
The specifications of Triethylene Glycol can vary depending on the specific grade and application. Here are some general specifications:

• Chemical formula: C6H14O4
• Molecular weight: 150.17 g/mol
• Appearance: Colorless liquid
• Density: Approximately 1.12 g/cm³
• Boiling point: Approximately 285-290 °C
• Solubility: Miscible with water and many organic solvents
• Purity: Typically, not less than 99% or higher (depending on the grade)

Application:

1. Industrial applications: Triethylene Glycol finds extensive use in various industrial applications, including:

   • Solvent: TEG is used as a solvent for dyes, resins, oils, and other organic compounds.
   • Humectant: It is employed as a humectant in textile processing, paper production, and printing inks to prevent drying and improve moisture retention.
   • Dehydration agent: TEG is used as a dehydrating agent in natural gas processing, where it removes water and impurities from the gas stream.
   • Plasticizer: It can function as a plasticizer, improving the flexibility and workability of materials such as polymers, resins, and adhesives.
   • Heat transfer fluid: TEG is utilized as a heat transfer fluid in various systems, including heating, ventilation, and air conditioning (HVAC) systems, as well as in industrial processes.

2. Gas dehydration: TEG is commonly employed in the natural gas industry for gas dehydration. It has a high affinity for water and is used to remove moisture from natural gas streams, preventing the formation of hydrates and corrosion in pipelines and equipment.

3. Personal care products: Triethylene Glycol is used in certain personal care products, such as skin creams, lotions, and cosmetics, where it acts as a humectant and moisturizer, helping to retain moisture in the skin.

Features:

1. Hygroscopic properties: Triethylene Glycol is highly hygroscopic, meaning it has a strong affinity for water and readily absorbs moisture from the surrounding environment. This property makes it effective in applications involving water removal or moisture retention.

2. Low volatility: TEG has relatively low volatility, allowing it to be used in applications requiring stable performance over extended periods, such as heat transfer fluids.

3. Chemical stability: Triethylene Glycol exhibits good chemical stability, making it resistant to degradation and suitable for use in various industrial processes.

4. Low toxicity: TEG is considered to have low toxicity and is generally regarded as safe for specified applications. However, proper handling and safety precautions should always be followed.

5. Versatility: Triethylene Glycol's properties, such as its solubility, hygroscopicity, and heat transfer capabilities, make it a versatile compound suitable for diverse applications in different industries.

Triethylene glycol description

triethylene glycol, teg, or triglycol is a colorless odorless viscous liquid with molecular formula hoch2ch2och2ch2och2ch2oh. it is used as a plasticizer for vinyl. it is also used in air sanitizer products, such as "oust" or "clean and pure". when aerosolized it acts as a disinfectant. glycols are also used as liquid desiccants for natural gas and in air conditioning systems. it is an additive for hydraulic fluids and brake fluids and is used as a base for "smoke machine" fluid in the entertainment industry.

 

Triethylene glycol use

1, was used as a solvent for nitrocellulose, various resins, gums, rocket fuel, plasticizing agent and diesel additives, used for gas chromatography and organic synthesis. teg is mainly used for air drying solvents, aromatic hydrocarbon extraction agent. also used for printing ink, softening agent, moisturizing agent and air conditioning system of disinfectants.

2, as natural gas, oil field associated gas and carbon dioxide excellent dehydrating agent; excellent organic solvent; air sterilization agent; polyvinyl chloride, polyvinyl acetate resin, glass fibers and asbestos pressing plate of triethylene glycol lipids increase plasticizer etc. is also used to organic synthesis, such as production brake oil of high boiling point and good performance at low temperature.
