Vinylessigsαure - Reference Information
| Use | for organic synthesis. polymer monomer synthesis. |
| production method | is obtained by hydrolysis of butene-3-nitrile. The butene-3-carbonitrile and concentrated hydrochloric acid are heated together, and a large amount of ammonium chloride precipitate is generated after the reaction, and the temperature rises quickly. After refluxing and reacting for 15min, water is added, and the upper acid layer is separated out and distilled under reduced pressure, fractions were collected at 70-72 °c (1.2kPa). |
