How is Triethylene Glycol distinguished from Diethylene Glycol and Polyethylene Glycol?

Triethylene Glycol is the defined compound CAS 112-27-6, formula C₆H₁₄O₄. Diethylene Glycol has CAS 111-46-6, while Polyethylene Glycol is a distribution of chain lengths. They are not interchangeable on a mass basis; confirm the full identity, CAS number, molecular-weight basis and chromatographic profile.

Which specifications should be agreed for industrial Triethylene Glycol?

Set GC assay, water, color, acidity, ash, density or refractive index and limits for Ethylene Glycol, Diethylene Glycol and heavier glycols as the process requires. State the analytical methods and whether purity is reported by area or mass. Review the batch COA against the intended dehydration, plasticizer or synthesis use.

What should be confirmed for bulk TEG storage and delivery?

TEG is hygroscopic, so use clean, dry, compatible tanks or drums with protected vents and sealed transfer connections. Agree package or tanker format, previous-cargo controls, loading temperature, allowable water pickup, production date and storage history. Sample the delivered lot without exposing it unnecessarily to humid air.
