From Infogalactic: the planetary knowledge core
The carbylamine reaction is a chemical test for detection of primary amines.[1] In this reaction, the analyte is heated with alcoholic potassium hydroxide and chloroform. If a primary amine is present, the isocyanide (carbylamine) is formed which are foul smelling substances.
For example, the reaction with ethylamine:
