Common peroxide formers
WebJul 5, 2024 · Simply put, peroxide-forming chemicals (PFCs) are a class of compounds that have the ability to form shock-sensitive explosive peroxide crystals. Many of the organic solvents commonly used in laboratories have the potential to form explosive peroxide crystals. If used in the science laboratory, strict safety protocols are required. WebIsopropanol is not one of the notorious peroxide formers, but it will eventually do so in the presence of oxygen (with or without light - the process is autocatalytic). When I was a …
