3-Methylaminopropionitrile Uses
3-Methylaminopropionitrile (CAS NO.693-05-0) can be used in organic synthesis.
3-Methylaminopropionitrile Production
Derived by the addition from acrylonitrile and methylamine . Add the methylamine - ethanol solution into the reaction pot,then stirring cooled to 5°C;maintaining 10-20°C, dropping acrylonitrile - ethanol solution about 3h end. At 15°C below to continue to respond 1h, atmospheric pressure steam to the ethanol, then vacuum distillation, collecting 112-115 (13.3kPa) fractions.
