What is Diphenyl sulfone?
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.
The Uses of Diphenyl sulfone
Diphenyl sulfone was identified as the preferred solvent. Diphenyl sulfone is chemically and thermally stable as compared to dimethyl sulfoxide.
The Uses of Diphenyl sulfone
Ovicide; acaricide.
The Uses of Diphenyl sulfone
Phenyl Sulphone undergoes deoxygenation with Mg-MeOH at room temperature.
