Triethylene glycol

Brief Overview
Triethylene glycol, also known as TEG, appears as a colorless odorless viscous liquid. It has relatively good hygroscopic properties which aids in the dehumidification of fluids. It is widely used in manufacturing of vinyl polymers as a plasticizer. It is also used in sanitizing products such as disinfectants.

Manufacturing Processes
Triethylene glycol is manufactured by two processes, oxidation and hydration. Ethylene is oxidized at the beginning, with silver oxide catalyst, to produce ethylene oxide. Subsequently, the oxide is hydrated to produce Triethylene glycol.
