31.21.1.1.3 Variation 3: Using Fuming Nitric Acid

DOI: 10.1055/sos-SD-031-01277

Aitken, K. M.; Aitken, R. A.Science of Synthesis, (2007311186.

Fuming nitric acid can be used in the nitration of aromatic compounds with one or more deactivating substituents, including cases where multiple nitrations of an aromatic ring are attempted. In this section the use of over 70% HNO3 (d >1.4g·mL1) is considered. In some references, red fuming nitric acid, which is 100% nitric acid prepared from potassium nitrate and concentrated sulfuric acid, is used.[‌22‌]
