Properties and stability
1. Chemical properties: It has the chemical properties of primary amines and can also undergo various reactions on double bonds. For example, it adds with halogen and hydrogen halide to form halopropylamine. Reacts with benzene to obtain β-aminocumene. Allylamine does not polymerize under the action of free radical catalysts. Reacts with cyclopentadiene to obtain 2,5-methylene-1,2,5,6-tetrahydrobenzylamine.

Storage method
Storage Precautions[27] Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 29°C. The packaging must be sealed and must not come into contact with air. They should be stored separately from oxidants, acids, and food chemicals, 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
1. Allylamine can be obtained by reacting allyl chloride with ammonia: The reaction is carried out in equipment with a reflux device, and the reflux reaction of allyl thioisocyanate and 20% hydrochloric acid is carried out for 15 hours. The reaction was concentrated, diluted with water when crystals appeared, and then the allylamine was distilled off while adding alkali solution dropwise. The collected crude product can be refined by fractionation.
Purpose
1. Used as polymer modifier and diuretic, raw material for organic synthesis, etc.
2. Intermediates used in the manufacture of pharmaceuticals, and solvents for organic synthesis and production. [28]
