Allylaminy

Allylamine, also known as 3-aminopropene, is an organic compound with the formula C3H7N. It is a primary amine containing a vinyl group, making it a reactive vinyl amine. In its pure form it is a colorless liquid at room temperature with a characteristic amine odor; it has a molar mass of 57.1 g/mol and is miscible with water.

Allylamine readily undergoes polymerization and oxidation and is typically stored with stabilizers or inhibitors. It is a volatile, flammable liquid and should be handled under appropriate safety precautions to avoid contact with skin, eyes, and inhalation exposure.

Industrial production of allylamine is commonly achieved by catalytic hydrogenation of acrylonitrile to give 3-aminopropene. Alternative routes include aminolysis or hydroamination of allyl derivatives, but acrylonitrile hydrogenation is the principal method.

Applications: As a vinyl amine, allylamine serves as a reactive monomer for the production of poly(allylamine) and other polymers, as well as a chemical intermediate for surfactants, corrosion inhibitors, and specialty resins. The related poly(allylamine) polymers are used in water treatment as flocculants and in paper and textile processing.

Safety: Allylamine is corrosive and irritating to skin, eyes, and the respiratory tract. It can form hazardous nitrosamines under nitrosating conditions, and it reacts with oxidizers. It is flammable and should be stored and used with appropriate engineering controls and personal protective equipment.
