| Use | for organic synthesis. |
| production method | the strongly basic resin with quaternary ammonium salt deposited on polystyrene was added to water and heated to 45 °c, acrylonitrile was slowly added dropwise under the liquid level, and the reaction was completed at 45-47 ° C. For 4-5H. The reactants were distilled off from excess acrylonitrile under atmospheric pressure, and then distilled under reduced pressure to collect the 119-120 ° C. (0.13kPa) fraction to obtain the product 2-cyanoethyl ether. Yield 77%. |
