Acetic acid to Oxalic Acid
I was wondering what the reduction of acetic acid to oxalic acid formula would be. I can't figure it out nor can I find an answer on google
Elements Collected: 19/81 (Excluding all radioactive, using placecard for those)
Any tips or good sources are welcome.

It would be an oxidation, for one thing. I'm not sure if it's a feasible reaction, but it can be easily balanced using the half-reaction method and
your choice of oxidizing agent.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

Writing a oxidation equation is nothing, for instance:
HOOC-CH3 + 2 H2O === > HOOC-COOH + 6 H<sup>+</sup> + 6 e<sup>-</sup>
Finding an oxidant that can do it is quite another.
Oxalic acid is very cheap and OTC in most places.

I did this reaction by Aqua regia and got good yield of oxalic acid.
I tried to make Glyoxylic acid by this way but i was unsuccessful, it seems this is impossible to stop this oxidation at aldehyde step.

Aqua regia oxidizes acetic acid to oxalic, but not further to CO2 ? I can't believe, do you have any more details/references on it?

Common white sugar (sucrose) can be oxidised to oxalic acid with nitric acid. There's a thread on it somewhere on this forum.

No future oxidation occur.
I used same procedure for making Glyoxylic acid from Glyoxal but i used Acetic acid instead of Glyoxal.
