Diphenyl sulfone Chemical Properties,Usage,Production

Chemical Properties

Diphenyl sulfone is a sulfone compound having two S-phenyl substituents. It is a crystalline powder that is soluble in organic solvents. It has been found in plants like Gnidia glauca and Dioscorea bulbifera. It has a role as a plant metabolite.

Diphenyl sulfone is formed under certain conditions by the action of aqueous sulfuric acid on benzene. It is used as a high temperature solvent. Such high temperature solvents are useful for processing highly rigid polymers, e.g., PEEK, which only dissolve in very hot solvents.

Uses

Ovicide; acaricide.

Uses

Phenyl Sulphone undergoes deoxygenation with Mg-MeOH at room temperature.

Uses

Diphenyl sulfone was identified as the preferred solvent. Diphenyl sulfone is chemically and thermally stable as compared to dimethyl sulfoxide.

Definition

ChEBI: A sulfone compound having two S-phenyl substituents. It has been found in plants like Gnidia glauca and Dioscorea bulbifera.
