TRIETHYLENE GLYCOL (TEG)
2,2鈥?-(1,2-ethanediylbis(oxy)) ethanol

TRIETHYLENE GLYCOL (TEG) is a straight-chain dihydric alcohol aliphatic compound terminated on both
ends by a hydroxyl group. It is a clear, practically colorless and odorless, hygroscopic liquid at room
temperature.

HOCH2CH2(OCH2CH2)2OH
APPLICATIONS 鈥? unsaturated polyester resins 鈥? polyester polyols
鈥? lubricant and coupling agents 鈥? plasticizers
鈥? humectants and dehydrating agents 鈥? solvents
Triethylene glycol is used as a dehydrating agent for natural gas; a solvent and
lubricant in textile dyeing and printing; a plasticizer; a raw material for the production of
polyester resins and polyols; a humectant; a constituent of hydraulic fluids; a selective
solvent for aromatics.

PRODUCT SAFETY POLICY
It is the product safety policy of Huntsman Corporation to provide our customers with information on the safe
handling and use of our products. The Material Safety Data Sheet (MSDS) should always be read and understood
thoroughly before handling the product and adequate safety procedures should be followed. Information on the
toxicity, environmental and industrial hygiene aspects of our products may be found in the MSDS. Precautionary
measures include: use only with adequate ventilation; avoid breathing vapor, mist or gas; avoid contact with eyes,
skin and clothing; keep container closed; wash thoroughly after handling.

TOXICITY AND SAFETY
For additional information on the toxicity and safe handling of this product, consult the Material Safety Data
Sheet prior to use of this product.

HANDLING AND STORAGE
Triethylene glycol (TEG) is a stable, non-corrosive chemical with high flash point. Since it is hygroscopic, storage
vessels must be designed to minimize moisture pickup. Other possible contaminants are iron and oxygen. For
longer-term storage, or where iron contamination and color are objectionable, resin linings or stainless steel and
aluminum vessels are recommended. Linings based on phenolic and epoxy resins are satisfactory. Zinc or zinc
alloys should not be used in glycol service. For longer-term color stability, it is recommended that the product be
stored under an inert atmosphere.

Cast-iron or centrifugal pumps with stainless shafts and impellers are satisfactory. Rubber-lined or rubber-bound
gaskets should be avoided. Flexible graphite filled or stainless steel double-jacketed gaskets are usually effective
larger gaskets. Stainless steel winding with flexible graphite filler piping gaskets performs well. Pipe thread
lubricants based on corrosion inhibiting zinc compounds or a graphite based lubricant with aluminum are generally
satisfactory; however, glycols are excellent penetrants and leaks may be present where hydrostatic testing has
indicated a tight system. Therefore, the system should be rechecked after the glycol has been added.

Low pressure stainless steel steam coils in storage tanks and steam tracing of transfer lines may need to be
provided in cases where low environmental temperatures may make pumping of the product difficult. Transfer or
storage tanks can be readily cleaned by flushing with water and steam.

AVAILABILITY
Product is available in tank cars, tank trucks or non-returnable drums (520 pounds net). Containers are stainless
steel, aluminum or suitably lined. Certain government regulations may apply at the time of shipment. Samples are
available by contacting our sample department at 1-800-662-0924.
