Diethylene Glycol (DEG), with the chemical formula C4H10O3 and CAS number 111-46-6, is a crucial organic compound widely utilized across numerous industries. It is characterized as a colorless, transparent, and viscous liquid at room temperature, possessing strong hygroscopicity, a high boiling point, and excellent solubility. Its molecular structure, featuring two hydroxyl groups and two ether bonds, imparts both hydrophilic and powerful solvent properties, making it an indispensable component in various industrial processes.

One of DEG's most prominent features is its efficient solvent performance. It exhibits strong solubility for a wide range of polar substances, including dyes, resins, and nitrocellulose. This makes it an ideal choice for formulating high-quality coatings, inks, and other specialized chemical preparations where effective dissolution and dispersion are critical. Beyond its solvent capabilities, DEG also boasts significant moisture absorption and moisturizing properties, allowing for the precise adjustment of environmental humidity in applications such as textile fiber processing and tobacco moisture retention.

The high boiling point stability of DEG, typically ranging from 244-246°C, ensures it is not easily volatile at elevated temperatures. This characteristic is particularly valuable in high-temperature processes like polyester resin synthesis, where stability and consistent performance are paramount. Furthermore, with a low freezing point of approximately -10.5°C, DEG can be effectively used as an antifreeze component, especially when compounded with other glycols like ethylene glycol or propylene glycol, providing robust protection in industrial circulating water systems and heat transfer media.

As a highly reactive chemical intermediate, Diethylene Glycol actively participates in esterification and etherification reactions. This makes it a vital building block for the synthesis of a diverse array of chemical products, including plasticizers (such as DEG benzoate), surfactants, triethylene glycol, and morpholine derivatives. Its versatility extends to being used as a gas dehydrating agent in natural gas processing, an adhesive plasticizing component, and a dispersant in ceramic slurries, showcasing its broad utility across various manufacturing sectors.

Industrial grade Diethylene Glycol typically exhibits a purity of at least 99.0%, with a density at 20°C ranging from 1.116 to 1.120 g/cm³. The moisture content is kept below 0.2%, and its chromaticity is typically less than 15 Pt-Co, ensuring consistent quality for demanding industrial applications. For more specific requirements, high-purity grades with even tighter specifications are available upon request.

It is crucial to emphasize that while Diethylene Glycol is a highly effective industrial chemical, its handling requires strict adherence to safety protocols. DEG is toxic to the kidneys and nervous system, and its use is strictly prohibited in human-contact areas such as food, drugs, and cosmetics. During handling, it is imperative to wear appropriate personal protective equipment, including chemical-resistant gloves, goggles, and respiratory masks. Storage should be in sealed containers in cool, well-ventilated areas, away from strong oxidants, acids, bases, and heat sources, to prevent degradation or hazardous reactions. Proper waste management according to hazardous chemical regulations is also essential to protect the environment.
