Question

How will you separate primary, secondary and tertiary amines using hinsenberg reagents ( 3 marks ) ​

Answer 1

The Hinsberg test, which can distinguish primary, secondary, and tertiary amines, is based upon sulfonamide formation. In the Hinsberg test, an amine is reacted with benzene sulfonyl chloride. If a product forms, the amine is either a primary or secondary amine, because tertiary amines do not form stable sulfonamides.

ANSWER :-

Hinserberg test is employed to separate primary, secondary and tertiary amines from a mixture. In this test the mixture of amines is treated with benzene sulphonyl chloride (hisenberg's reagent) followed by treatment with aqueous KOH (5%) solution and then shaken with ether in a separatory funnel.
