Properties and stability
Avoid contact with oxides. After decomposition, carbon monoxide, carbon dioxide, nitrogen oxides, and hydrogen cyanide can be produced.
Storage method
Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30℃. Keep container tightly sealed. They should be stored separately from oxidants, alkalis, and alkali metals, 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
Stir and maintain 0℃, add sodium cyanide aqueous solution to the mixture of formaldehyde and ammonium chloride, halfway through the addition, At the same time, glacial acetic acid was added dropwise. After the addition is completed, stir 1.5h, filter out the precipitate, wash with water, and dry to obtain methylene aminoacetonitrile, yield 61-71% SPAN>.
Purpose
Organic synthesis intermediates.
