Perfluorobutanesulfonic acid (PFBS) is a chemical compound having a four-carbon fluorocarbon chain and a sulfonic acid functional group. It is stable and unreactive because of the strength of carbon–fluorine bonds. It can occur in the form of a colorless liquid or a corrosive solid. Its conjugate base is perfluorobutanesulfonate (also called nonaflate) which functions as the hydrophobe in fluorosurfactants. Since June 2003, 3M has used PFBS as a replacement for the persistent, toxic, and bioaccumulative compound perfluorooctanesulfonic acid (PFOS) in its Scotchgard stain repellents. 3M markets surfactant with PFBS in two fluorosurfactants.

Making Calcium Peroxide (CaO2)
In today’s video we are making calcium peroxide from sodium hydroxide, calcium chloride and hydrogen peroxide. Calcium peroxide is an oxidizing agent and it could be used to make oxygen by simply heating it. Our yield was low but we managed to make some. Just to put it somewhere: the produ

Epoxidation of Alkenes - DMDO, mCPBA, & NaOCl (IOC 26)
In this episode, I discuss the epoxidation of electron-rich and electron-poor olefins, using peracids, DMDO, hydrogen peroxide, and sodium hypochlorite (NaOCl). *Note: for some reason, I didn't manage to pronounce MMPP correctly; it's full name is magnesium monoperoxyphthalate. *WARNING*

Glycerol and Potassium Permanganate
When glycerol and dry potassium permanaganate are added together, an extremely exothermic reaction occurs. The potassium permanaganate is an extremely strong oxidizer and it completely oxidizes the glycerol to water and carbon dioxide.
