DMSO2 (Dimethyl Sulfone) is an organic compound of extreme
chemical and thermal stability. As such, it has been used as a high-temperature
reaction solvent in elimination and nucleophilic aromatic substitution reactions.
A wax-like solid at room temperature, DMSO also sublimes away easily, and
deposits little decomposition residue.
Key Applications for DMSO2 (Dimethyl
Sulfone)
As a high temperature reaction solvent. When used at high temperatures,
the low degree of decomposition minimizes solvent-related process impurities.
The polarity of DMSO2 is useful in stubborn elimination and substitution
reactions.
Additive to extractive distillation processes. Dimethyl Sulfone modifies
the solvent properties of common extractive solvents used in the extraction
of benzene, toluene, and xylene (BTX) to increase process selectivity
and loading.
In powder metallurgy, compacts are formed from which DMSO2 may be sublimed
leaving no residual contamination.
Lithium battery technology.
Cosmetics use DMSO2 in formulations where it is claimed to be anti-inflammatory
and penetrate deep within the skin's surface to moisturize, soften and
rejuvenate dry, aging, or damaged skin.
To reduce the melt viscosity of vinylidene chloride-containing polymers,
DMSO2 has been used.
