| Use | for organic synthesis. |
| production method | is obtained by addition of acrylonitrile and methylamine. The methylamine-ethanol solution was added to the reaction Pan, cooled to 5 °c with stirring, and the acrylonitrile-ethanol solution was added dropwise, maintained at 10-20 °c for about 3 hours. After the reaction was continued for 1H below 15 ° C., ethanol was distilled off under normal pressure, and then distilled under reduced pressure to collect the 112-115(13.3kPa) fraction, I .e., 3-methylaminopropionitrile. |
