Application
– Oil and Gas: Triethylene glycol is used for dehydration of natural gas / CO₂ gas (its main application)
– Chemicals: Raw material for resin plasticizers, extraction solvent for aromatics, ink / paint solvent
– Cosmetics: Triethylene glycol can be used as a moisturizer in skin care products, a solvent for fragrance, and an air disinfection medium
– Machinery: Special brake oil, hydraulic oil, heat-resistant anti-freezing heat transfer medium
– Medicine: Solvent for drug extraction, auxiliary material for external preparations
✨ Product Features
1. Exceptionally strong moisture absorption capacity, recyclable and reusable (oil and gas industry)
The core advantage of triethylene glycol: selectively absorbs moisture in gases without absorbing hydrocarbons; after saturated water absorption, it can be heated for regeneration and reused repeatedly. It is a standard dehydration agent in the natural gas industry, preventing hydrate freezing blockage in gas pipelines and equipment corrosion, reducing operation and maintenance costs, and is the mainstream agent for global natural gas purification.
2. High boiling point, low volatility, excellent thermal stability
The boiling point of triethylene glycol is as high as 285℃, and the volatility loss is very small under high-temperature conditions; it is not prone to decomposition during high-temperature regeneration and has low loss during long-term continuous operation, making it suitable for high-temperature heat transfer, extraction, and solvent systems. Compared with ethylene glycol and diethylene glycol, it has better thermal stability at high temperatures.
3. Excellent dissolution performance, broad-spectrum solvent
Triethylene glycol has both alcohol and ether structures, which can dissolve in water and also dissolve resins, nitrocellulose, dyes, inks, fragrances, and many organic raw materials; it is used as an aromatic hydrocarbon extraction solvent, a high-temperature solvent for coatings/inks, and a medium for organic synthesis reaction media.
4. Low irritation, good safety, wide application scenarios
Triethylene glycol is slightly toxic and has low skin irritation; it can be used in compliance grades for skin care moisturizers, external medical solvents, wet wipes for in-vitro antibacterial; it can also be used as a plasticizer intermediate and synthesized into triethylene glycol ester plasticizers, with good plasticizing effect, low migration rate, and low temperature resistance.
Packaging and Storage
Packaging: 25kg per drum; 200L iron drums; 1000kg per barrel; ISO Tank tank.
Storage environment: Cool, dry and well-ventilated warehouse; recommended temperature 10~30℃, not exceeding 40℃; keep away from direct sunlight, heat sources and open flames.
Separation storage: Store separately from strong oxidants and strong acids, and prohibit mixed storage; prepare leakage containment and sand adsorption materials at the storage area.
FAQ
Q: Why did the color turn yellow after receiving the goods?
A: The main reasons are: ① Oxidation occurs due to long-term high temperature and sunlight exposure; ② There is a lot of air in the barrel, and it is in contact with oxygen for a long time. It is recommended that customers keep the barrel full and sealed in a cool place for storage; for high-demanding conditions, nitrogen-filled protective packaging can be selected.
Q: What are the hazards if it comes into contact with the human body?
A: It is low toxicity; prolonged skin contact will cause loss of fat and dryness; splashing into the eyes will be irritating; do not ingest. Just wear goggles and nitrile gloves during operation.
Q: How long is the delivery period?
A: For stock items, it takes 3-7 days.
Q: How long is the shelf life of TEG?
A: The shelf life is 2 years.
Q: What is the minimum order quantity (MOQ) for the order?
A: For regular barrel packaging, the MOQ is 1 barrel (200kg/220kg); for samples, it can be arranged.
