The main uses for triethylene glycol are based upon its hygroscopic quality. It is used as a dehydrating agent for natural gas pipelines where it removes the water from the gas before being condensed and reused in the system. It is also a dehumidifying agent in air-conditioning units.
What is C4H10O3?
DI(Hydroxyethyl)ether | C4H10O3 – PubChem.
What is the boiling point of triethylene glycol?
545°F (285°C)
Triethylene glycol/Boiling point
What is the difference between ethylene glycol and triethylene glycol?
Tetraethylene Glycol (TTEG) has similar properties to the lower ethylene glycols, but has a higher boiling point and lower volatility. It is principally used, as the main solvent constituent is aromatic solvent extraction.
Is triethylene glycol a peg?
Triethylene Glycol is a specific three-unit chain, whereas PEG-4 is a polymer with an average of four units, but may contain polymers ranging from two to eight ethylene oxide units. In the same manner, other PEG compounds, e.g., PEG-6, are mixtures and likely contain some Triethylene Glycol and PEG-4.
Is diethylene glycol the same as ethylene glycol?
Ethylene glycol is an individual molecule derived from ethylene oxide. Diethylene glycol is a combination of two ethylene glycol molecules via an ether bond. There is no ether bond in ethylene glycol. Ether bond links the two ethylene glycol molecules.
Is DEG c4h10o3 a compound mixture or element?
Diethylene glycol (DEG) is an organic compound with the formula (HOCH2CH2)2O. It is a colorless, practically odorless, poisonous, and hygroscopic liquid with a sweetish taste. It is a four carbon dimer of ethylene glycol.
Is triethylene glycol the same as ethylene glycol?
Ethylene Glycol (EG) is produced by hydration of ethylene oxide. As a result, minor amounts of Diethylene Glycol (DEG) and Triethylene Glycol (TEG) is produced as a byproduct. Ethylene Glycol (EG) is by far the largest volume glycol product.
Is triethylene glycol water soluble?
This liquid is miscible with water, and at standard atmospheric pressure (101.325 kPa) has a boiling point of 286.5 °C and a freezing point of -7 °C. It is also soluble in ethanol, acetone, acetic acid, glycerine, pyridine, aldehydes; slightly soluble in diethyl ether; and insoluble in oil, fat and most hydrocarbons.
What is triethylene glycol and how does it work?
Triethylene glycol is placed into contact with natural gas, and strips the water out of the gas. Triethylene glycol is heated to a high temperature and put through a condensing system, which removes the water as waste and reclaims the TEG for continuous reuse within the system.
What are the different types of glycol ethers?
The members of this category are glycol ethers derived from ethylene glycol, diethylene glycol, and triethylene glycol. This category does not contain glycol ethers based on propylene glycol, dipropylene glycol, or tripropylene glycol.
When did high molecular weight glycol ethers go out of category?
The effect of this modification is that many high molecular weight glycol ethers were excluded from the category. As described in the final rule, this modification was made retroactive for the 1993 reporting year for reports due July 1, 1994.
What is the CAS number for glycol ethers?
Section 1.3 Individually Listed Glycol Ethers There are two chemicals, 2-methoxyethanol (CAS number 109-86-4) and 2-ethoxyethanol (CAS number 110-80-5) that are on the individual chemical list and CAS number list (40 CFR 372.65(a) and (b)).
