Why it is difficult to prepare pure amines by ammonolysis of alkyl halides?

Ammonolysis of alkyl halides leads to the formation of mixture of primary, secondary, tertiary amines along with the quaternary salts. This is because the primary amine formed can react with the alkyl halide to form the secondary amine, which in turn will again react with the alkyl halide to form the tertiary amine, which also reacts with the alkyl halide leading to the formation of quaternary salt. Thus such a reaction would form a mixture of all the four compounds and it will be difficult  to get the prue amine.
