Carbolic soap Carbolic soap Carbolic soap is a mildly antiseptic soap containing carbolic acid and/or cresylic acid, both of which are phenols derived from either coal tar or petroleum sources. In 1834, German chemist Friedlieb Ferdinand Runge discovered a phenol, now known as carbolic acid, which he derived in an impure form from coal tar. In August 1865, Dr. Joseph Lister, 1st Baron Lister applied a piece of lint dipped in carbolic acid solution onto the wound of an eleven-year-old boy at Glasgow Royal Infirmary, who had sustained a compound fracture after a cart wheel had passed over his leg. After four
Methanesulfonic acid is formed. Methanesulfonic acid is considered a particularly suitable supporting electrolyte for electrochemical applications, where it stands as an environmentally friendly alternative to other acid electrolytes used in plating processes. Methanesulfonic acid is also the electrolyte of choice in zinc-cerium (see cerium(III) methanesulfonate) and lead-acid (methanesulfonate) flow batteries. Methanesulfonic acid is also a primary ingredient in rust and scale removers. It is used to clean off surface rust from ceramic, tiles and porcelain which are usually susceptible to acid attack. Methanesulfonic acid Methanesulfonic acid (MsOH) is a colorless liquid with the chemical formula CHSOH. It is the simplest of the
