Diethylene Glycol (DEG), identified by its CAS number 111-46-6, is a significant chemical intermediate that bridges basic petrochemicals to a vast array of downstream products. Understanding its synthesis and applications is crucial for professionals in chemical manufacturing and R&D. As a specialized manufacturer, we provide high-quality DEG to fuel these industrial processes.

Commercially, Diethylene Glycol is primarily produced as a co-product during the manufacturing of Ethylene Glycol through the hydration of Ethylene Oxide. The reaction involves the sequential addition of Ethylene Oxide to water, with Diethylene Glycol and Triethylene Glycol being formed as byproducts alongside Monoethylene Glycol. Another direct synthesis route involves the reaction between Ethylene Glycol and Ethylene Oxide under controlled conditions. The efficiency and purity of these production methods are key factors for manufacturers to consider when sourcing.

The versatility of Diethylene Glycol as a chemical intermediate is evident in its wide range of applications. It is a vital component in the production of unsaturated polyester resins, which are used in fiberglass-reinforced plastics, coatings, and molding compounds. DEG also serves as an intermediate in the synthesis of surfactants, plasticizers, and various esters and ethers, each finding distinct applications in industries ranging from cosmetics to construction.

In addition to its role as an intermediate, DEG’s inherent properties make it valuable in its own right. It is widely used as a solvent, a humectant, and in dehydration processes, as previously discussed. For businesses involved in chemical synthesis, obtaining a reliable supply of high-purity Diethylene Glycol is fundamental to achieving consistent yields and product quality. We encourage those looking to buy Diethylene Glycol to partner with experienced manufacturers who can guarantee product integrity.
