I have 10 lbs of oxalic acid that supposedly expires this March. What kind of reactions could I do with it for fun? Was thinking of making some sort of ferrioxalate again but it's light sensitive and annoying to deal with.
>inb4 eat it
also chemistry thread I guess

Is it a powder or solution? Powdered oxalic shelf life is usually 2-3 times what the manufacturers say

From the looks of it it's a hydro carbon when decomposed, try generating some electricity out of it and put the remaining substance on a fire to watch shit blow up

Internet says its reaction with permanganate is autocatalytic. Might be fun to see.

It's a bunch of fine needle-like crystals (quite small and almost powder-like). I suspected that the expiration date meant nothing, it just reminded me to do something with it.

I was thinking of making oxalyl chloride. Unfortunately I have no way to access TCCA right now unless I somehow make it myself. I could make it with PCl5, but again I would need to make the PCl5 (would need a lot of matchboxes hehe).
Maybe I'll try making formic acid, looking at the sciencemadness article is giving some good ideas.

It precipitates with alkaline earths to leave just about any acid, including sulfuric. If you're in the EU where the sale of appreciable amounts of sulfuric acid was recently banned, you can use oxalic acid and epsom salt to make sulfuric acid.

Nah, I wouldn't bother bringing phosphorus chemistry into the picture. Oxalyl Chloride would be the most useful thing you could make but its a nasty thing at best. You could make the methyl or ethyl acetopyruvate if you have sodium, there are preps on OrgSyn.

Neat website, I would need to make ethyl oxalate first. The same site calls for CCl4 in the synthesis with other complicated steps, so I was gonna try to do a simpler fischer esterification with just the oxalic acid, ethanol, and sulfuric acid. Of course I would also need sodium, but I'll just use a sodium-MgO aggregate (a lot easier). Looks really interesting, thanks for the idea, may try it out and post an update thread.
