Physicalproperties

First amine -------> first by pouring HCL solution and precipitate.

Secondary amines: HCL deposited and not solved.

Tertiary amines: material oil and consist of HCL is resolved.

 

 

Complications hins berg

– Amphoteric compounds give erroneous results.

– Some sodium salts of benzenesulfonamides of

primary amines are insoluble in the Hinsberg solution

and may appear to be secondary amines.

– Some tertiary amine hydrochloride salts are insoluble

in dilute HCl and water and may also appear to be

secondary amines
