Citric acid (and its uses)

sauveurdumonde - 19-11-2021 at 05:59

I bought 600g of very pure citric acid crystals from a local store for a few dollars. What should I do with it? I've tried making some copper salts but they're rather soluble in water...

I would like to do a conversion into smaller carboxylic acids, like malic, but I am not really sure where to start.

There are several threads already on the conversion of citric acid into acetone dicarboxylic acid, itaconic acid, esters, amides, pyridine derivatives, pentabromoacetone etc. I suggest that you try using the search engine and check out a few of these.

If I remember corectlly, you must heat solution to precipitate copper citrate. I never made copper citrate, but calcium citrate can be made that way.

citrazinic acid is easy to make and has the neat property of fluorescing. Chemplayer made a vid on it: https://www.bitchute.com/video/tlVMeE33uHD7/.

Hmmm. I have 5kg that I was given. I have given little thought on what to do with it.

I think I'll try that, and make some transition metal salts. It would be interesting if they were fluorescent too... Colourful + fluorescent is always nice

Now, I just need to make some urea (hopefully not from my pee)
