I am going to synthetise isopropyl salicylate. From what I have read on phillysim.org (pdf) the formation of ethyl salicylate can be catalyzed by boric acid. I could use sulfuric acid but it would be much more convenient with boric acid. Ethanol and isopropanol have some differences, so I am not sure if it works for both of them.
Has anyone tried this? Does it work? Would it be better to just use sulfuric acid?
