For professionals in the chemical industry, particularly those involved in the production of dyes and pigments, understanding key intermediates is paramount. N-Ethyl-N-hydroxyethylaniline, identified by CAS number 92-50-2, stands out as a significant organic compound with extensive applications. This article delves into its properties, manufacturing processes, and the importance of sourcing it from reputable suppliers to ensure product quality and consistency.

N-Ethyl-N-hydroxyethylaniline is characterized by its molecular formula C10H15NO and a molecular weight of 165.23. It typically appears as a clear, colorless to yellow or orange liquid, though it may darken during storage. This compound serves as a critical building block, primarily in the synthesis of azo compounds. Azo compounds are fundamental to the vibrant palette used across industries, from textiles and inks to plastics and coatings. The specific structure of N-Ethyl-N-hydroxyethylaniline, with its ethyl group and hydroxyethyl group attached to the aniline nitrogen, imparts unique reactivity that is essential for forming the characteristic azo linkage.

Synthesis and Quality Considerations

The synthesis of N-Ethyl-N-hydroxyethylaniline often involves the reaction between N-ethylaniline and ethylene oxide. Various patented methods exist to optimize yield and purity. For instance, one common approach utilizes a controlled reaction in an autoclave under specific temperature and pressure conditions, often in the presence of a catalyst like taurine, to achieve high yields. As a manufacturer, maintaining strict quality control throughout the synthesis process is crucial. This includes monitoring reaction parameters, purification steps, and final product analysis to ensure the intermediate meets the required purity levels, typically 99% or higher.

Applications in Dye and Pigment Manufacturing

The primary utility of N-Ethyl-N-hydroxyethylaniline lies in its role as an intermediate for dyes and pigments. It is instrumental in producing a wide array of colorants, including Disperse Red 1, Disperse Red 8, Disperse Red 13, Disperse Red 76, Orange 10, Acid Red 53, and various Basic Red dyes. For procurement managers and R&D scientists, selecting a reliable manufacturer and supplier is key to securing a consistent supply of this vital intermediate. Purchasing directly from a manufacturer in China can offer significant advantages in terms of cost-effectiveness and accessibility.

Choosing a Supplier

When looking to buy N-Ethyl-N-hydroxyethylaniline, several factors should be considered. The purity of the product is critical for achieving desired color strength and stability in the final dye or pigment. A supplier's ability to provide detailed technical data, such as Certificates of Analysis (CoA), is also important. Furthermore, ensuring a stable supply chain, competitive pricing, and responsive customer service are vital for long-term partnerships.
