Nitric acid fuming nitric acid at concentrations above 86%. Nitric acid is the primary reagent used for nitration – the addition of a nitro group, typically to an organic molecule. While some resulting nitro compounds are shock- and thermally-sensitive explosives, a few are stable enough to be used in munitions and demolition, while others are still more stable and used as pigments in inks and dyes. Nitric acid is also commonly used as a strong oxidizing agent. Commercially available nitric acid is an azeotrope with water at a concentration of 68% HNO, which is the ordinary concentrated nitric acid of commerce. This
Benzenesulfonic acid sometimes called alkaline fusion, initially affords the phenoxide salt: The process has been largely displaced by the Hock process, which generates less waste. Benzensulfonic acid is commonly used as the active ingredient in laundry detergent used in clothes washing machines. Benzenesulfonic acid is often used to convert to other specialty chemicals. A variety of pharmaceutical drugs are prepared as benzenesulfonate salts and are known as besilates (INN) or besylates (USAN). In a diluted form, it is also used as a polymer remover stripping agent. Benzenesulfonic acid Benzenesulfonic acid (conjugate base benzenesulfonate) is an organosulfur compound with the formula CHOS. It
