Reaction of Amines with Strong Acids Amine Salts 

Amines react with strong acids to form alkylammonium salts. An example of this reaction for a primary amine and HCl is as follows  

Complete the following acid-base reaction, and name the product. 

This type of reaction is used to separate or extract amines from neutral or acidic water-insoluble substances. Consider, for example, a mixture ofp-toluidine and p-nitro-toluene, which might arise from a preparation of the amine that for some reason does not go to completion (eq. 11.10). The amine can be separated from the unreduced nitro compound by the following scheme
