Properties and stability
1. It is corrosive, can cause burns, and is harmful in contact with skin. Appropriate protective clothing should be worn when using it in large quantities.
Storage method
This product should be sealed and stored away from light.
Synthesis method
1. Obtained from catalytic hydrogenation of β-hydroxypropionitrile. Add β-hydroxypropionitrile, Raney nickel, ethanol, and ammonia into the autoclave, vent hydrogen to 2.94MPa, maintain the hydrogen pressure at 100-120°C, and continue to keep it warm for 2 hours until no hydrogen is absorbed. After the reaction is completed, the temperature is lowered, and Raney Nickel is recovered by filtration. The filtrate is distilled under reduced pressure and the 90-92°C/2.0kPa fraction is collected. The content is over 95% and the yield is close to 70%.
Purpose
1. Available organic synthesis intermediates. Used in the synthesis of cyclophosphamide, cardiodin and other drugs.
2. Used in the synthesis of cyclophosphamide, cardiodin and other drugs, and also used in the synthesis of DL-panthenol
3. Used in organic synthesis
