Ammonium organic salt form the coresponding amines upon heating, for example
ammonium formate --> formamide
ammonium acetate --> acetamide
ammonium oxalate --> oxamide e.t.c.
Have the nitrate/perchlorate salts of those amides ever studied ? Like formamide/acetamide nitrate/perchlorate oxamide dinitrate/diperchlorate ?

Amides aren't very strong bases, so they don't form stable salts.

You’re gonna want to read up on some introductory organic chemistry. Amides have completely different reactivity than
amines. I would suggest specifically reading up on the definitions of functional groups, and pKa.

I am pretty sure the perchlorate salts exist since perchloric acid is s strong acid. There was a topic in the past about oxamide dinitrate but it was
not any deep investigation.

Maybe it can, but amides get protonated on the carbonyl oxygen, like other carbonyl compounds, not on nitrogen like amines.
Edit: and even if amides can be protonated by perchloric acid, it’s not gonna happen in an aqueous solution to a significant extent.

I know you can make the salts of some amides- one of my labmates made acetamide hydrochloride once in grad studies. It turned out to be extremely
hygroscopic and entirely unsuitable for whatever it was he wanted it for.
