Phenol From Glow Sticks


In a glow stick chemical reaction, a tiny amount of phenol is produced from the reaction, now carnival time is coming up in a month and i can get 100 glow sticks for 10 dollars + more glow stick inside the show bag, if i do one big reaction (open am all up then combine together all at once) how do i safely extract the phenol and maybe as well the solvent if it hasn't all reacted

Isn't this the fourth topic you have started today? Whatever, it doesn't matter.

I was under the impression that it was trichlorophenyl oxalate in most glowsticks (TCPO). So I suppose that you could salvage some 2,4,6-trichlorophenol by what you are suggesting.

Why do you want phenol? Do you have any use for it? You may have more luck running a diazotisation on aniline to phenol. Judging from your posts you watch Youtube videos a lot. The youtube user "myst32yt" has a pretty good video on the process. You might want to check it out.

yeah its the 3rd post.... i like posting what i want to know, if i wanna do myst32YT version, i need aniline and i dont have it. i want phenol to make Phenolphthalein and i dont see any videos on extracting phenol with this method so i wanna try it out

For another method Try Google:

Making it from Aspirin tablets is simplier.
First, extract the acetylsalycilic acid from the tablets: dissolve them in IPA, filter and crystallise adding cold water (about 5 times the IPA).
Then hydrolyse the ASA to salicylic acid with HCl (refluxing for 30 minutes).
Now just decompose the SA by rapidly heating it and it'll give you phenol.

Do you have a reference for the decomposition of salicylic acid? I have been searching, but I can't find anything. It seems like a great way to phenol.

In fact I read about the SA thermal decomposition on the Internet, but I never searched for a reference.
Anyway i found one: Marek Wesołowski, Thermal decomposition of salicylic acid and its salts. Unfortunately i can't access it because the site that hosts it is down: http://linkinghub.elsevier.com/retrieve/pii/0040-6031(79)85001-7
Hopefully it'll be back soon :)

phenol can be made from by heating SA with CaO

redox is correct, the only phenol would be 2,4,6-trichlorophenol, and that would only be found in the used glow sticks, which you might be able to find really cheap after a concert or other event. It is rather toxic and smelly, I believe, as it is one of the compounds that has been found in small amounts in some medicines after pallets treated with it where used to store the products and the plastic bottles absorbed it.

But there is no useful amount of phenol in glow sticks. There are other ways to make it or find it, so I would look at the threads on that as a starting point.

How would i be able to remove it from the remains of a glow stick? im thinking about doing a large scale reaction from this so i can get good results

it wouldnt be worth the effort you would next to nothing, unless u extract that little glass tub prior to breaking it, that has concentrated peroxide but depending on the brand it might be contaminated

Yeah, im planning on cutting open the tube and mix the chemicals once all out of the tube... is the hydrogen peroxide 30% and is it mixed with anything?

i tested some and was around 18%, mines was contaminated but it might differ by brand, honestly the h2o2 is the only thing worth even extracting make sure u use disposable labware cuz the green goo is a pain in the ass to get off glassware

the organic solvent that is in the glass tube, is it possible to extract that aswell or is it too hard to get the dye out of the solvent?

the dyes make a colored solution when dissolved into the solvent... in the glow sticks i get, the glass tube has the colored solution while the plastic tube is the clear solution

O ok. Mines was the glass tub had clear solution. Take a bit of the clear solution and mix with mno2 if gas evolution is observed then that's the h202
