5-Sulfosalicylic acid is a strong acid capable of protonating water. It forms a new theophylline complex, which was investigated by X-ray photoelectron spectroscopy (XPS). It forms 1:1 proton-transfer compounds with the ortho-substituted monocyclic heteroaromatic Lewis bases. Their crystal structures have been studied. | [Synthesis]
Nitration reaction: Salicylic acid is mixed with concentrated sulfuric acid and concentrated nitric acid, and the nitration reaction is carried out at low temperature to obtain nitrosalicylic acid. The reaction needs to be matched with conditions such | [Purification Methods]
Crystallise the acid from H2O. Alternatively, it is converted to the monosodium salt which is crystallised from H2O and washed with a little H2O, EtOH and then Et2O. The acid is recovered by acidifying. The S-4-chlorobenzylisothiuronium salt has m 181o (from dioxane). [Beilstein 11 H 411, 11 II 232, 11 III 704.] |
