| Hazard Information | Back Directory | [Chemical Properties]
Naphthalene-1,3,5-trisulfonic acid [6654- 64-4]. C10H8O9S3, Mr 368.34, is extremely soluble in water; the sodium salt crystallizes as the tetrahydrate. | [Uses]
Naphthalene-1,3,5-trisulphonic Acid is a residue found in environmental samples that is a result of the degredation of domestic and industrial use surfactants. | [Definition]
ChEBI: Naphthalene-1,3,5-trisulfonic acid is a naphthalenesulfonic acid. | [Production Methods]
Naphthalene and 65 % oleum are added simultaneously to sulfuric acid monohydrate over a period of 32 h at 30 – 35℃. The mixture is then heated at 50℃ for 1 h, 70℃ for 1 h, and finally 90℃ for 7 h. This procedure minimizes formation of the 1,3,6-isomer, but a purer product may be obtained by using isolated naphthalene-1,5-disulfonic acid as starting material. | [References]
