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;
