Phenol - Sciencemadness Wiki
2024年3月5日 · Phenol, especially phenol water has been successfully neutralized with Fenton's reagent. If concentrated phenol is used, the resulting gasses which will aerosolize some phenol and byproducts. This is dangerous in an enclosed area, as phenol is irritant and toxic if inhaled. Since phenol is water soluble, it's best to use diluted aqueous solutions.
Phenol Storage - Powered by XMB 1.9.11 - Sciencemadness
2011年12月5日 · Phenol should be pretty stable, so I don't see any issues with storage. I can't think of any way that phenol should react with air or water, even if it were to absorb some water it could likely be dried by putting under vacuum for a while. I have used bottles of phenols that were years old with no problems.

2022年11月30日 · Butylated hydroxytoluene (BHT), also known as dibutylhydroxytoluene, is an organic compound, chemically a derivative of phenol, widely for its antioxidant properties, such as preservative for many reagents and other products.
Fenton's reagent - Sciencemadness Wiki
2019年9月4日 · Fenton's reagent will convert benzene into phenol: C 6 H 6 + FeSO 4 + H 2 O 2 → C 6 H 5 OH. Some chemists think Fenton's reagent contains iron(IV). A disadvantage of using the Fenton oxidation to remove organic contaminants is the formation of Fe(OH) 3 precipitate, which contains large quantities of adsorbed organic compounds.
