    Triethylene Glycol Formula

    C6H14O4Molecular Formula

    HOCH2CH2OCH2CH2OCH2CH2OH

    CAS Registry Number 112-27-6

    Synonyms Glycol-bis(hydroxyethyl) ether 2,2-[1,2-ethanediylbis(oxy)] bis-ethanolTriglycolTEGT3EG TriEG

    Triethylene glycol is a transparent, colorless, low-volatility, moderate-viscosity, water-soluble liquid.Under normal conditions, there is no detectableodor; under high vapor concentrations, a slightlysweet odor may be detected. It is completelymiscible with water and many organic liquids.Triethylene glycol has properties similar to otherglycols and may be used preferentially inapplications requiring a higher boiling point,higher molecular weight or lower volatility thandiethylene glycol.

    The hydroxyl groups on triethylene glycol undergothe usual alcohol chemistry giving a wide varietyof possible derivatives. Hydroxyls can beconverted to aldehydes, alkyl halides, amines,azides, carboxylic acids, ethers, mercaptans,nitrate esters, nitriles, nitrite esters, organic esters,peroxides, phosphate esters and sulfate esters.

    Triethylene glycol may be used directly as aplasticizer or modified by esterification. Thesolubility properties of triethylene glycol areimportant for many applications. End-uses fortriethylene glycol are numerous. (See Table 1.)

    Health EffectsTriethylene glycol is slightly toxic. See the latest Material Safety Data Sheet for the most current exposurelimits, health, first aid, and toxicology information.

    Environmental InformationTriethylene glycol has been shown to be relatively nontoxic to bacteria and aquatic life. See the latestMaterial Safety Data Sheet for current information.

    Biodegradation The biodegradability of triethylene glycol was evaluated by extended-term biochemical oxygen demand(BOD) tests. Using unacclimated biomass, the BOD tests indicated that triethylene glycol is slowlybiodegraded. However, with acclimation of the microorganisms, as in a wastewater treatment plant,biodegradation increases to a rapid rate.

    EPA (40CFR) Permitted Use 180.1001(d) Inert ingredient (deactivator) for use in formulations applied to growing crops only up

    to the time of harvest.

    (a) For complete information on conditions of use, refer to the applicable section in the Code of Federal Regulations.(b) This application requires triethylene glycol containing a maximum of 0.1 wt % diethylene glycol. Triethylene Glycol, High

    Purity Grade, meets this FDA requirement.

    The foregoing is provided for your convenience. The FDA and/or other Federal and state regulatory agencies may haveadditional requirements and/or may periodically amend requirements. It is your obligation to be familiar with and comply withall laws, rules, and regulations applicable to your use of triethylene glycol.

  • Storage and Handling This information is offered as a guide in planningbulk storage facilities for glycols. Glycols aregenerally considered to be stable, non-corrosivechemicals with high flash points. Under ordinaryconditions, all of these chemicals can be stored inmild steel vessels. For long-term storage, or if traceiron contamination and the development of colorare objectionable in any of the glycols, a storagevessel lined with a baked-phenolic resin, an air-drying epoxy-phenolic resin, or a vinyl resin or astainless steel or aluminum tank is suggested. Zincor galvanized iron is not recommended, andcopper or copper alloys may cause productdiscoloration.

    It is not general practice to use an inert gas in thevapor space of glycol storage tanks, because allchemicals in this family have high boiling pointsand the vapors in the tanks are relatively non-flammable. However, if extremely low watercontent is required, consistent with a long storageperiod, a nitrogen blanket can be used to excludeatmospheric moisture and air. Blanketing withnitrogen will also minimize low-level oxidation, ifnecessary for the desired application. The inertgas prevents air oxidation in order to maintainproduct within acidity specifications. Increasedacidity enhances iron pickup from steel vessels.Alternatively, a desiccant unit can be installed onthe tank vent line to dry incoming air.

    If above ground outside storage is planned, it maybe necessary to install provisions for heating tanksand lines. Many glycols have a moderately highfreezing point or become relatively viscous atsevere winter temperatures. However, excessivetemperature can cause undesirable degradation ofglycols. Automatic controls are suggested to limitthe temperature of the contents to 120F (49C).

    In cold climates, it is generally desirable to makeprovisions for draining the pump and the transferlines if they are outside the building. If this is notfeasible, it may be necessary to insulate and steamtrace or otherwise heat the transfer lines toprevent freezing of the product. Care must be

    taken in such an application, because continuedexposure of glycols to high temperatures, greaterthan 120F (49C), will result in productdegradation. Transfer piping of mild steel isgenerally used.
