‌Applications of N-ethyl-N-hydroxyethylaniline‌

‌Dye intermediates‌: N-ethyl-N-hydroxyethylaniline is mainly used as an intermediate for disperse dyes and acid dyes. It plays a key role in the synthesis of dyes, especially in improving the dispersion performance of dyes in synthetic fibers. ‌Pigment intermediates‌: In addition to being a dye intermediate, N-ethyl-N-hydroxyethylaniline can also be used as an intermediate for organic pigments and is widely used in the pigment manufacturing industry. ‌Synthesis of other chemicals‌: The hydroxyethyl group on the nitrogen atom of N-ethyl-N-hydroxyethylaniline can be prepared into a variety of aniline derivatives through reactions such as aminolysis, saccharification, acetylation, chlorination, and dehydration condensation, further expanding its application range. ‌N-ethyl-N-hydroxyethylaniline is an important chemical that is widely used in the synthesis of dyes, pigments, and fine chemicals. It is an indispensable part of the chemical industry.

When handling N-ethyl-N-hydroxyethylaniline, follow the following safety guidelines:

‌Personal protection‌: Wear appropriate protective clothing and gloves to avoid direct contact between chemicals and skin. ‌
‌Operating environment‌: Operate only outdoors or in a well-ventilated area to avoid inhaling vapor or mist. ‌
‌Eye protection‌: If accidentally contacted with eyes, rinse immediately with plenty of water and seek medical attention. ‌
‌Emergency treatment‌: In case of leakage, quickly leave the scene to a place with fresh air; keep the airway open and give oxygen in case of breathing difficulty; if breathing stops, immediately perform artificial respiration and seek medical attention. ‌

Storage conditions: Store sealed in a cool, dry place away from light to ensure chemical stability. ‌
Following the above safe handling guidelines can effectively reduce the risk of harm to humans and the environment caused by N-ethyl-N-hydroxyethylaniline. At the same time, relevant safety training should be received regularly to ensure that sufficient safety awareness and emergency response capabilities are available when handling such chemicals.
