Benzylamine is a chemical compound consisting of a benzyl group and a functional group containing an amine group. It is the simplest aromatic amine having the amino group in the side chain.

Properties

Benzylamine is a colorless slightly flammable fumes in the air liquid with ammoniacal odor which is completely miscible with water. It decomposes above a temperature above 300 ° C, toluene, benzonitrile, stilbene, bibenzyl, ammonia, nitrogen oxides, carbon monoxide and carbon dioxide produced.

Representation

For benzylamine there are various syntheses:

• Reaction of benzyl chloride with ammonia
• Reaction of N- benzylphthalimide with hydrazine according to the principle of the Gabriel synthesis
• Of benzyl bromide and acetamide and subsequent cleavage of the amide bond
• Reduction (hydrogenation ) of benzamide or benzonitrile with lithium aluminum hydride

Use

It is a frequently used starting material in synthetic organic chemistry.

Safety

The vapors of benzylamine to form (65 ° C, ignition temperature 390 ° C flash point) with air to form an explosive mixture.
