Yield:151-18-8 45%

Reaction Conditions:

with ammonia at 100; under 6750.68 Torr; for 4 h;Temperature;Pressure;

Steps:

1 Example 1 Synthesis of β-Aminopropionitrile
8L liquid ammonia and 2L acrylonitrile were put into the high pressure reaction kettle, heated to 100 ° C under stirring, the control pressure was 9 kg / cm 2 , the reaction was 4 hours, the heating was stopped, and when the temperature dropped to about 65 ° C,The exhaust valve was opened to vent the ammonia gas, and the reaction liquid was transferred to a rectification vessel, and distilled under reduced pressure to collect a fraction at 95 ° C to obtain 1 L of liquid β-aminopropionitrile in a yield of 45%.
