Diethanolamine (DEA), known by its CAS number 111-42-2, is a versatile organic compound that finds extensive use across a multitude of industries. Its unique chemical structure, combining amine and alcohol functionalities, makes it an invaluable ingredient in sectors ranging from detergents and cosmetics to gas sweetening and pharmaceuticals. For B2B procurement managers and product developers, understanding the core properties, applications, and sourcing channels for Diethanolamine is essential for making informed purchasing decisions. This article aims to provide a comprehensive overview, including how to effectively buy Diethanolamine from reliable manufacturers.

The chemical properties of Diethanolamine contribute to its broad applicability. As a secondary amine, it exhibits basic characteristics and can react with acids. The presence of two hydroxyl groups allows it to act as a diol, participating in esterification and etherification reactions, and critically, reacting with isocyanates to form urethane linkages. It is known for its hygroscopic nature and its tendency to supercool, often appearing as a colorless, viscous liquid at room temperature, although pure DEA is a white solid. Its miscibility with water and solubility in polar solvents further enhance its utility in various formulations. These properties make it an excellent surfactant, emulsifier, and corrosion inhibitor.

The industrial applications of Diethanolamine are diverse. In the detergent industry, it is a precursor for diethanolamides, which improve lathering and viscosity in soaps and detergents. In cosmetics, it contributes to the creamy texture and emulsification in shampoos, conditioners, and lotions. The oil and gas industry relies on DEA for gas sweetening, efficiently removing H₂S and CO₂ from natural gas. Furthermore, it serves as a chemical intermediate in the synthesis of morpholine and other specialty chemicals. Understanding these applications helps buyers identify the best grade and purity of Diethanolamine for their specific needs.

For businesses looking to procure Diethanolamine, sourcing from a reputable manufacturer in China offers distinct advantages, including competitive Diethanolamine price and access to large-scale production capacities. When selecting a supplier, it is crucial to prioritize purity, consistency, and reliability. Look for manufacturers that provide comprehensive documentation, such as Certificates of Analysis (CoA), detailing product specifications, purity levels (typically ≥99% for industrial grades), and impurity profiles. This due diligence ensures that the purchased Diethanolamine meets the required standards for your specific application.

Logistics and customer support are also key factors in the procurement process. An established Diethanolamine supplier will offer flexible packaging options and efficient shipping solutions, whether by sea, land, or air. Familiarity with international trade terms (Incoterms) and customs procedures is also beneficial. Responsive customer service and technical support can further streamline the purchasing experience, assisting with product selection, order processing, and troubleshooting.

In summary, Diethanolamine is a vital chemical intermediate with widespread industrial applications. By thoroughly understanding its properties, applications, and by diligently selecting a reliable Diethanolamine manufacturer in China that prioritizes quality, competitive pricing, and efficient logistics, businesses can secure a consistent and cost-effective supply of this essential compound. When you decide to buy Diethanolamine, making an informed choice of supplier is critical for your operational success.
