Procurement of Phenol

JacobM - 8-1-2022 at 12:24

I need a fair bit of phenol (25g) for an upcoming experiment on the Bargellini reaction. I have made a little phenol from salicylic acid as per methods discussed on this forum. I don't like this method because it involves distilling the phenol, which smells terrible and makes the likelihood of exposure higher. It also has a tendency to clog my distillation fittings and be a pain in the a$$ to clean. Are there any methods I can use to obtain phenol besides salicylic acid decarboxylation and making it from aniline?

Edit: it's never the initial distillation but the redistillation that causes issues. The phenol always gets stuck inside the vacuum adapter.

Why not just buy some?? I don’t see this as being particularly difficult to acquire. Seems to be readily available from a variety of sellers.

I've thought of doing this. However I can only find liquid phenol on Ebay of a decent purity. Liquid phenol has water, which I'm not sure this reaction is amenable to.
There's a Ukrainian seller selling it, but I doubt it would get through customs.

Have you seen any sellers?

Why wouldn’t it get through customs?? If you are based in the USA, a Google search gave me several domestic sellers that have it.

Like whom?

Phenol can be obtained from pyrolysis polycarbonate(compact discs) with zinc chloride and followed distillation tar collect fraction 180-185C
It can be produced in large volume if you have many compact discs and fuel(wood)

this also produces p-isopropenylphenol
See:

WARNIGNG: It produces very acrid smoke due to benzoquinone.

I just got 500g from LabDirectLLC, and it was very cheap It even was solid when I recieved it in mid July. But if you arent far I might be able to get a sample sent out to you. I dont mind sending it. It might be a delay though me because I moving closer to my university for my new job.

I bought from the "Ukrainian seller" on Ebay. The shipment came through just fine, but I'm based in EU. The shipment was prompt and the product seems to be just like advertised. Unfortunately that means it's a bit red and probably needs to be distilled anyhow.

If you're in the EU I can also highly recommend LiMac: https://www.limac.lv/catalog/params/category/91115/item/3733...
They ship from Latvia and have a decent catalogue.
