Properties and stability
Prohibited withStrong oxidants, strong acidsContact.
Storage method
Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. Keep container tightly sealed. They should be stored separately from oxidants, acids, and alkalis, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials.
Synthesis method
It is obtained by hydrolysis, addition and degradation of acrylonitrile; another production method is to obtain this product by hydrogenation of ethylenediaminoacetonitrile.
Purpose
Used as an intermediate for fine chemicals, it can produce the antiarrhythmic drug procainamide and the local anesthetic dibucaine hydrochloride And enzyme inhibitors and so on. It is also used to produce auxiliary products, for example, it is used to prepare Sapamine BCH.
