Hi everyone :)

I'm a swissguy, sorry if I make errors with writing in english.

My simple question is, if its possible to nitrate gallic acid. And what kind of chemical it is after?

Kind regards

Gallic acid is easy to oxidise, I believe you end up mostly with oxalic acid. Its ethers can be nitrated, however it tends to decarboxylate in the process.

An online search quickly turns up

No, gallic acid + nitric acid gives a mix of products; mostly CO2, H2O, and oxalic acid.
