Preparation of Triethylene Glycol (TEG)
Triethylene glycol is prepared commercially as a co-product of the oxidation of ethylene at high temperature, in the presence of a silver oxide catalyst. The ethylene oxide is then hydrated to yield mono, di, tri, and tetra ethylene glycols. Here’s a more detailed explanation of the process:
Oxidation of Ethylene: The commercial production of TEG often starts with the oxidation of ethylene (C2H4) at high temperatures in the presence of a silver oxide (Ag2O) catalyst. This process leads to the formation of several products, including ethylene oxide (EO) and other oxygenated compounds.
Collection of Ethylene Oxide: Ethylene oxide (EO) is a key intermediate product in this process and is collected for further use in the production of glycols.
Hydration of Ethylene Oxide: The collected ethylene oxide is then subjected to hydration, which is the addition of water (H2O) to ethylene oxide. This hydration process leads to the formation of various glycols, including monoethylene glycol (MEG), diethylene glycol (DEG), triethylene glycol (TEG), and sometimes even tetraethylene glycol (TTEG).
Fractionation and Separation: After the hydration step, the mixture contains a combination of these glycols along with unreacted ethylene oxide and other by-products. Fractionation and separation techniques are used to separate and isolate the individual glycols based on their different boiling points. This step allows for the purification and collection of TEG.
Purification and Packaging: The separated TEG is then further purified to remove any remaining impurities. Once the desired level of purity is achieved, the TEG product is packaged and prepared for distribution and use in various industrial applications.
