The amine which reacts with p-toluenesulphonyl chloride to give a clear solution which on acidification gives insoluble compound is a primary amine such as ethyl amine C 2 H 5 NH 2. C 2 H 5 NH 2+ CH 3- C 6 H 4- SO 2- Cl xrightarrow OH - CH 3- C 6 H 4- SO 2- NHC 2 H 5 xrightarrow KOH CH 3- C 6 H 4- SO 2- N - C 2 H 5 K + xrightarrow H +CH 3- C 6 H 4- SO 2- NHC 2 H 5 It is Hinsberg's test used to distinguish between primary, secondary and tertiary amine.
