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
Crotonic acid of plastics, it may be copolymerized with vinyl acetate. Crotonyl chloride reacts with "N"-ethyl-2-methylaniline ("N"-ethyl-o-toluidine) to provide crotamiton, which is used as an agent against scabies. Crotonic acid Crotonic acid ((2"E")-but-2-enoic acid) or is a short-chain unsaturated carboxylic acid, described by the formula CHCH=CHCOH. It is also called crotonic acid because it was erroneously thought to be a saponification product of croton oil. It crystallizes as needles from hot water. The "cis"-isomer of crotonic acid is called isocrotonic acid. Crotonic acid may be obtained by several methods: Crotonic acid crystallizes in long needles or as large panels in the monoclinic
