Carbylamine reaction

From Wikipedia, the free encyclopedia

The Carbylamine reaction is a chemical test for detection of primary amines.

The carbyl amine reaction with ethyl amine

Here ethyl amine is heated with alcoholic Potassium hydroxide and chloroform. This liberates the foul-smelling and toxic compound ethyl isocyanide.

The carbyl amine reaction with aniline

Here when Aniline is heated with the same reactants, the foul-smelling and toxic compound Phenyl isocyanide is liberated.

The carbylamine test is not given by secondary and tertiary amines.
