| | 1-Naphthalenesulfonic acid Usage And Synthesis |
| Chemical Properties | grey fine crystalline powder | | Uses | 1-Naphthalenesulfonic acid was used as template molecule to prepare new non-covalent molecularly imprinted polymer for solid-phase extraction of naphthalene sulfonates. | | Definition | ChEBI: Naphthalene-1-sulfonic acid is a naphthalenesulfonic acid. | | General Description | Mechanism of metabolism of 1-naphthalenesulfonic acid by green algae Scenedesmus obliquus has been investigated. | | Synthesis | Using o-nitrobenzene as a solvent, naphthalene, chlorosulfonic acid, and o-nitrobenzene were mixed in a molar ratio of 1:1.1:3, and sulfonation was carried out at 0-5℃ to directly obtain 1-naphthalenesulfonic acid with a purity of approximately 97%. | | Purification Methods | Crystallise the acid from conc HCl and twice from H2O. The S-benzylisothiuronium salt has m 137o (from aqueous EtOH). [Beilstein 11 H 155, 11 III 383, 11 IV 521.] |
