allylamino

Allylamine, also known as allyl amine, is an organic compound with the chemical formula C3H7N. It consists of a vinyl group (CH2=CH–) attached to an amino group (–NH2) through a methylene bridge, giving the structure CH2=CH–CH2–NH2. It is a colorless liquid at room temperature with a strong, irritant odor and is miscible with water.

Industrial production and handling: Allylamine is typically produced on an industrial scale by catalytic amination of allyl halides, or by related amination routes from allyl derivatives. It is a reactive monomer that readily participates in vinyl polymerization, and it is usually stabilized during storage to prevent uncontrolled exothermic polymerization. It has a boiling point around 80–85°C and is miscible with water and many organic solvents.

Applications and polymers: Allylamine is used as a monomer for poly(allylamine) and other cationic polymers, which find applications in water treatment, papermaking, coatings, and biotechnology. It also serves as an intermediate in the manufacture of dyes, resins, surfactants, and agrochemicals.

Safety and handling: Allylamine is corrosive and can irritate skin, eyes, and the upper respiratory tract. It is toxic by inhalation and ingestion and can cause severe burns on contact. It may form hazardous nitrosamines under nitrosating conditions; exposure should be minimized, and handling should occur with appropriate ventilation and personal protective equipment. It should be stored in tightly closed containers away from oxidizers and acids, with stabilizers or inhibitors used to prevent polymerization.
