Properties and stability

Stable under normal temperature and pressure.

Incompatible materials:Strong oxidants, strong acids, strong bases.

Storage method

Save in a dry and cool place

Synthesis method

Obtained from the amination of acrylonitrile. Cool the dry autoclave to 35℃ or below, add acrylonitrile, diphenylamine, and tert-butyl alcohol in sequence, stir 5min, Add liquid ammonia, control the temperature at 100-109℃, the pressure at about 1MPa, keep warm and stir 4h. Cool to below 10℃ and stop stirring when the pressure drops to normal pressure. Recover tert-butanol under reduced pressure at 65-70℃ (14.7-21.3kPa) to obtain crude product 3-Aminopropionitrile, the crude product is distilled under reduced pressure and collected 66-105℃ (1.33-4.0kPa) fraction to obtain 3- aminopropionitrile.

Purpose

Used as organic synthesis and pharmaceutical intermediates.
Intermediate for the synthesis of alanine and pantothenic acid; can be obtained by reduction1,3-Diaminopropane; reacts with phosgene to produce isocyanate, which can further react with p-nitroaniline to produce a sweetener that is sweeter than sugar350 times; the hydrogen on ammonia can be substituted by aliphatic hydrocarbons, alicyclic hydrocarbons, aromatic hydrocarbons and heterocyclic rings to generate Corresponding alkylaminopropionitrile;
