| | 2,2'-Biphenol Usage And Synthesis |
| Chemical Properties | Beige to greyish-beige powder | | Uses | 2,2'-Dihydroxybiphenyl, is an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff. | | Production Methods | 2,2'-Dihydroxybiphenyl is obtained by alkaline fusion of biphenylene oxide at ca. 300 ℃ (sometimes catalyzed by fluorene or carbazole) or by debutylation of 3,3',5,5'-tetra-tert-butyl-2,2'-dihydroxybiphenyl, which itself is produced by the oxidative coupling of 2,4-di-tert-butylphenol. 2,2'-Dihydroxy-5,5'-dimethylbiphenyl can be synthesized accordingly. | | Definition | ChEBI: A member of the class of hydroxybiphenyls carrying hydroxy groups at positions 2 and 2'. | | Safety Profile | Poison by intraperitoneal andintravenous routes. Human mutation data reported. Whenheated to decomposition it emits acrid smoke andirritating fumes. | | Purification Methods | Crystallise the biphenyl repeatedly from toluene, then sublime it at 60o/10-4mm.
