| | N-Ethyl-N-hydroxyethylaniline Usage And Synthesis |
| Chemical Properties | clear yellow liquid after melting | | Uses | 2-(N-Ethylanilino) ethanol was used in the preparation of azo compound N-ethyl-N-(2-hydroxylethyl)-4-(2-cyano-4-nitrophenylazo) aniline (AZ1)2. | | General Description | 2-(N-Ethylanilino) ethanol couples with 2-amino-5-formylthiophene during the synthesis of nonlinear optical chromophores. It undergoes azo coupling with 2-cyan-4-nitroaniline to yield azochromophore AZ1. | | Synthesis | 1. The autoclave was purged with nitrogen and protected by nitrogen with 24.2 kg (200 mol) of N-ethylaniline, 8.9 kg (202 mol) of ethylene oxide, and 242 g (1.9 mol) of taurine. 2. The autoclave was closed, making sure that the lid was screwed on tightly. 3. The heating system was turned on, and the temperature was ramped up to 102°C at a rate of 1°C/min before stopping the heating, and the temperature of the reaction will naturally rise to 133°C. 4. Maintain the reaction at 133°C for 4 h. 5. Upon completion of the reaction, the reaction mixture was cooled to 40°C. 6. Open the autoclave and collect the product to give 32.8 kg of N-ethyl-N-hydroxyethylaniline in 99.4% yield. | | References | [1] Patent: CN108117492, 2018, A.
