PurposePurpose
• The object of this experiment is to identify an The object of this experiment is to identify an unknown amine or amine salt. First test to check unknown amine or amine salt. First test to check solubility. Second experiment represents a Hinsberg solubility. Second experiment represents a Hinsberg test for distinguishing between primary, secondary test for distinguishing between primary, secondary and tertiary amines.and tertiary amines.
Hinsberg TestHinsberg Test
• In Hinsberg test, the sulfonamides are distinguishable because In Hinsberg test, the sulfonamides are distinguishable because the derivative from a primary amine has an acidic hydrogen, the derivative from a primary amine has an acidic hydrogen, which renders the resulting salt soluble in Hwhich renders the resulting salt soluble in H22O. Whereas the O. Whereas the sulfonamide from the secondary amine is insoluble.sulfonamide from the secondary amine is insoluble.
