Nital is a solution of nitric acid and alcohol commonly used for etching of metals. It is especially suitable for revealing the microstructure of carbon steels. The alcohol can be methanol or ethanol. Mixtures of ethanol and nitric acid are potentially explosive. This commonly occurs by gas evolution, although ethyl nitrate can also be formed ...
A solution of nitric acid, water and alcohol, nital, is used for etching metals to reveal the microstructure. ISO 14104 is one of the standards detailing this well known procedure. [45] Nitric acid is used either in combination with hydrochloric acid or alone to clean glass cover slips and glass slides for high-end microscopy applications. [46]
Aqua fortis /spirit of nitre – nitric acid, formed by 2 parts saltpetre in 1 part (pure) oil of vitriol (sulfuric acid). (Historically, this process could not have been used, as 98% oil of vitriol was not available.) Aqua ragia /spirit of turpentine/oil of turpentine/gum turpentine – turpentine, formed by the distillation of pine tree resin.
Less-common or obsolete hypergolic propellants include: Aniline + nitric acid (unstable, explosive), used in the WAC Corporal [25] Aniline + hydrogen peroxide (dust-sensitive, explosive) Furfuryl alcohol + IRFNA (or red fuming nitric acid) – Copenhagen Suborbitals SPECTRA Engine [26] [5]: 27 Furfuryl alcohol + WFNA (or white fuming nitric ...
Mixture of nitric and acetic acids or nitric acid and acetic anhydride is commercially important in the production of RDX, as amines are destructed by sulfuric acid. Acetyl nitrate had also been used as a nitration agent. [14] [15] In the Wolffenstein–Böters reaction, benzene reacts with nitric acid and mercury(II) nitrate to give picric acid.
Most commonly, "mixed acid" (nitric and sulfuric acids) are used, but in the 1980s production of the nitrocellulose with magnesium nitrate as a dehydrating agent was started in the US. [4] In laboratory, phosphoric acid and phosphorus pentoxide or acetic acid and its anhydride may be used for the same purpose, or the nitroxylation can be ...
Fuming nitric acid contaminated with yellow nitrogen dioxide. Nitric acid (HNO 3) is by far the most important and the most stable of the nitrogen oxoacids. It is one of the three most used acids (the other two being sulfuric acid and hydrochloric acid) and was first discovered by the alchemists in the 13th century. It is made by catalytic ...
