Mellitic acid
I wanted to syntetize mellitic acid by reaction of graphite and KMnO4 in KOH but i didn´t get any product after neutralisation of solution and adding
Pb(NO3)2. Have you tried someone synthesis of mellic acid from graphite? Are there any other ways?

Use the search engine! There are at least two threads on mellitic acid covering all possible oxidizing agents and there are lots of references too,
including one that covers the use of permanganate as a partial (staged) oxidant after a preliminary oxidation with nitric acid IIRC. But be warned
graphite is a tough little b*****d and it only yields up mellitic acid to the very very patient. There are numerous other indirect route discussed
too.

Somehow I had never heard of mellitic acid before seeing this thread. Looks pretty neat. Well, I'll be adding it to the list of interesting things
that I'd like to try making.

I had never heard of it either. Mellite looks interesting too.
Kind of cool but I rather suspect I don't have the patience to produce it. Quoth Boffis, "graphite is a tough little b*****d and it
only yields up mellitic acid to the very very patient."

Figured I'd try my luck. Graphite's cheap and easy
to come by, and I finally found OTC potassium permanganate last week (two pounds for $10 at a resale store!)
I'm really going to need to make a fresh batch of nitric acid though. I have about 1 mL left of my last one, and I keep putting it off because it's
too hot to do anything involving additional heat. Summer is not a good time for chemistry when the lab is a garage in Texas. The proposed major El
Niño winter is looking pretty good to me right now.
