‌Morphology and basic properties of N-ethyl-N-hydroxyethylaniline‌

form:

It can be a liquid, specifically a colorless to light yellow or orange transparent oily liquid. The product may darken during storage.
It can also be semi-solid or solid, such as light yellow semi-solid or light yellow-brown solid, with a melting point of 35℃‌45.
Powder to block forms are also possible‌.

Other properties‌:

‌Acidity coefficient‌: pKa value is 14.66±0.10 (predicted value)‌.
‌Water solubility‌: At 20°C, the water solubility is 4.975g/L; however, there are also data showing that it is difficult to dissolve in water‌.
‌Molecular formula‌: C11H14N2‌3.
‌Vapor pressure‌: At 25℃, the vapor pressure is 0.0±0.6 mmHg‌.
In summary, N-ethyl-N-hydroxyethylaniline comes in various forms, including liquid, semi-solid and solid, and the color may change due to storage conditions.

‌Uses of N-ethyl-N-hydroxyethylaniline‌

‌Dye and pigment intermediates‌: N-ethyl-N-hydroxyethylaniline is mainly used as an intermediate for dyes and organic pigments, playing a key role in dye synthesis.
‌Disperse dye raw materials‌: It is an important raw material for dispersed yellow brown, dispersed orange, dispersed red 1, 8, 13 and 76, orange 10, acid red 53, basic red 18, 24 and other dyes. The hydroxyl group on the nitrogen atom Ethyl can improve the dispersion of dyes in synthetic fibers.
In addition, the hydroxyl group of N-ethyl-N-hydroxyethylaniline can be produced through aminolysis, saccharification, acetylation, chlorination, dehydration condensation and other reactions to produce a variety of aniline derivatives and dye intermediates, further broadening its scope of use. Application range‌.

In general, N-ethyl-N-hydroxyethylaniline is widely used in the dye and pigment industry and is one of the indispensable raw materials. At the same time, you also need to pay attention to its safety information to ensure that relevant regulations are followed during use to ensure the safety of personnel and the environment.
