Storage method
Storage Precautions[20] 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 and acids, 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
Obtained from the reaction of 2-ethylhexanol and ammonia. In the same set of batch kettle equipment, 2-ethylhexylamine, di(2-ethylhexyl)amine and tris(2-ethylhexyl)amine can be produced in rotation.
Refining method: Add metal sodium to dehydrate and then distill.
Purpose
1. Used as raw materials for medicines, dyes, pesticides, vulcanization accelerators, antioxidants, flotation agents, emulsifiers, etc. Mainly used in the production of (2-ethylhexylamine)-1-isopropyl-4-methyl-bicyclo(2,2,2)octyl chloride-2,3-dihydroxyimide. As a pesticide synergist, it has the same synergistic effect as piperonyl butoxide.
2. Used in synthetic detergents, rubber chemicals, oil additives and pesticides, etc. [21]
