‌‌ ‌‌Production process and uses of N-ethyl-N-cyanoethylaniline‌

‌Production process‌:

Use anhydrous AlC13 as a catalyst to catalyze the reaction between N-ethylaniline and acrylonitrile. The optimized conditions are: add 10% of the weight of N-ethylaniline anhydrous AlC13, react at about 80°C for 6-8 hours, and the conversion rate reaches 98.5%, with a yield of more than 97%.
Another process uses N-ethylaniline and chloroethanol under the catalysis of inorganic bases or salts to synthesize it at 120-130°C. The yield can reach 90%, but wastewater is formed in the process.
use:

Mainly used as the main raw material for dispersed yellow brown, dispersed orange and other dyes.
It is also used in chemical fields such as pharmaceutical intermediates, pesticide intermediates, amino compounds, nitrile compounds, etc.‌

‌N-ethyl-N-cyanoethylaniline is mainly used as a dye intermediate‌. Its market demand is mainly reflected in the dye industry, where it is used to produce dispersed yellow brown, dispersed orange and other dyes‌
. In addition, N-ethyl-N-cyanoethylaniline is also used in chemical fields such as pharmaceutical intermediates, pesticide intermediates, amino compounds, and nitrile compounds. The demand in these fields also forms part of its market.

In summary, the market demand for N-ethyl-N-cyanoethylaniline is mainly concentrated in the dye industry and some chemical industries, and it plays an important role as a key raw material in these industries.
