One type of amine is ethylamine. It is used in agricultural chemicals, mining chemicals, flotation agents, and in petroleum refining.
I have read that ethylamine should not be combined with strong acids or chlorine. It is used in organic synthesis as a reactive molecule. It is also used as a solvent.
Weirdly, it is also used in detergents. I saw it listed in the ingredients list (if you can call it that) on the back of a bottle of detergent.
