The Structure and Properties of Phenol-2,4-disulfonic Acid …
2014年5月2日 · The crystal and molecular structure of phenol-2,4-disulfonic acid dihydrate was determined by X-ray structure analysis. All hydrogen positions in the crystal structure were found using difference Fourier syntheses. Oxonium cations and acid anions were linked in the crystal structure by short H-bonds, and the phenol OH group participated in two ...
Preparation of picric acid - Chemistry Stack Exchange
The first product is probably 6-nitrophenol-2,4-disulfonic acid. In subsequent steps, the nitronium ion attacks at the 2- and 4-positions, displacing the sulfonic acid groups and forming 2,4,6-trinitrophenol (picric acid).
PHENOLDISULFONIC ACID | 96-77-5 - ChemicalBook
2023年10月29日 · Phenoldisulfonic acid is obtained by hydrolysis of the dichloride with ethyl alcohol and/or water. Nitration and reduction of this acid gives 5- amino-4-hydroxy-1,3-benzenedisulfonic acid. 4-Hydroxy-1,3-benzenedisulfonic acid accelerates the rearrangement of cumene hydroperoxide in the Hock – Lang phenol process.

MECHANISM OF NITRATION OF PHENOLSULPHONIC ACIDS
Isomeric phenolsulphonic acids and phenol-2,4-disulphonic acid were nitrated with 63% nitric acid. Chromato-polarographic method was used for separation and identification of the products. As known, nitro groups can be introduced: (1) directly into the benzene ring, (2) by substitution for sulphonic groups.
