Diphenyl sulfone(Cas 127-63-9) Usage

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	Diphenyl sulfone is a white, solid organosulfur compound, has a boiling point of 714.2 °F (379 °C) and is soluble in organic solvents. Diphenyl sulfone is used as a high temperature solvent for processing rigid polymers that only dissolve in very hot solvents, such as PEEK. It is also used in coating products, paper chemicals, and dyes. Diphenyl sulfone, a well-known strong electron acceptor, can form D-A structured compounds when connected with different donor substituents such as carbazole, diphenylamine, or acridine groups. These D-A compounds are extensively employed as thermally activated delayed fluorescence (TADF) emitters, host or transport materials in organic light-emitting diodes, but almost none of them have been applied in electrochromism.
Definition	ChEBI: A sulfone compound having two S-phenyl substituents. It has been found in plants like Gnidia glauca and Dioscorea bulbifera.
Flammability and Explosibility	Diphenyl sulfone can be flammable and explosive under certain conditions: Dust clouds: Fine dust (420 microns or less) created by grinding diphenyl sulfone can ignite and burn quickly and fiercely. Larger particles up to 1400 microns in diameter can also contribute to an explosion. Dust clouds can only ignite within a specific concentration range, similar to gases and vapors. Autoignition: Diphenyl sulfone has an autoignition temperature of over 475°C.
Purification Methods	Crystallise the sulfone from diethyl ether. It has been purified by zone melting. [Beilstein 6 H 300, 6 IV 1490.]

A series of multicolored cathodically coloring electrochromic (EC) materials based on diphenyl sulfone (DPS) moiety were synthesized and characterized. Herein two electron donors, N1,N1,N3,N3-tetraphenylbenzene-1,3-diamine (TPA) and 1,3-di (9H-carbazol-9-yl)benzene (MCP), were employed to construct donor-acceptor (D-A) or donor-acceptor-donor (D-A-D) small molecules with DPS as the acceptor.

The Tracer Study of the Reactions of Diphenyl Sulfone and Diphenyl Sulfoxide with Sulfur

Shigeru Oae, Shunichi Kawamura

, Bulletin of the Chemical Society of Japan, Volume 36, Issue 2, February 1963, Pages 163–167

Diphenyl sulfoxide-35S was reduced to the sulfide-35S nearly quantitatively by heating with sulfur at 280°C, while diphenyl sulfone did not react with sulfur at the same temperature. At around 300°C, diphenyl sulfone-35S started to react with sulfur and gave diphenyl sulride that lost nearly 75% of the original activity of 35S of the sulfone used. The main reaction of the sulfone was found not to be reduction, but substitution involving induced C-S cleavage and replacement with sulfur chain.
