Nitrating acid

The liquid which mixed strong sulfuric acid and concentrated nitric acid with the nitrating acid (こんさん British: mixed acid) at a volume ratio of 3:1. I am used for the nitration of aromatic compounds. I call even sulfuric acid and a combination except the nitric acid nitrating acid, but nitric acid refers to a mixture of the sulfuric acid integrally.

Reaction mechanism of the nitration

In nitrating acid, ニトロニウムイオン NO₂⁺ of 1 molecule arises from nitric acid 1 molecules and 2 molecules sulfate.

HN_O3 + 2H₂SO₄ → NO²+ + 2HS_O⁴- + H₃O⁺

ニトロニウムイオン which occurred is very strong 求電子剤 and produces a nitro-compound in response to aromatic compounds.
