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. [Beilstein 6 IV 6645.]
