Dmso Azeotrope

DMSO is a promising solvent for separating the azeotrope of isobutyl alcohol and isobutyl acetate by extractive distillation.

dimethyl sulfoxide (DMSO), etc. have been widely used for extractive distillation for mixture of THF and water. PSD is used to separate azeotropic mixture as.

DMSO recovery can be efficiently performed through aqueous solutions, even though originally contaminated with volatile and/or nonvolatile impurities.

This azeotrope is labeled A in the ternary diagram and contains 69.8 mole % isopropanol. It is possible to break this azeotrope using.

DMSO has been used as an industrial solvent since the mid-1800s. From about the mid-20th century, researchers have explored its use as an anti-inflammatory agent.

Note about Density: If the density of the solvent is greater then one (mass > 1.00) the solvent, if non-polar will sink below water. likewise if the density is less then one (mass < 1.00) the solvent, if non-polar, will float on the surface of the water. Azeotrope % weight /w water = 95.5%.

just wondering if there are any other tips fro getting rid of dMF, DMSO, etc. I read somewhere that toluene forms an azeotrope with DMF, so tried this and it worked!
