Question

What are amine salts?

Answer 1

These are the organic equivalents of ammonium salts, `NH_4X`.

Explanation:

Organic amines, `R_3N`, and ammonia, `NH_3` possess stereochemically active lone pairs, which can still donate to electrophiles:

#R_3N + R'-X rarr R_3R'N^(+)X^(-)

With 4 alkyl (or hydrocarbyl) groups bound the nitrogen centre, this is a quaternary ammonium salt. Of course, ammonium salts, `NH_4^(+)X^(-)`, are well known in inorganic chemistry.
