The high dissolving power of DMSO makes deuterated DMSO (DMSO-d6) a common solvent for NMR. One of the major drawbacks of DMSO is the difficulty of removal after a reaction. Its high boiling point (189 C) makes removal by rotovap very difficult. DMSO is also used as a reagent in a variety of different reactions. Common Uses:

level 1 · 3 yr. ago A colleague of mine once told me that he removed DMSO from NMR samples by blowing nitrogen over the sample overnight. This, of course, only will work with small quantities of DMSO. 5 level 2 Op · 3 yr. ago I thought about that as well, though I was looking for a super short time frame kind of trick. Thanks though! 1
If you cannot partition it into water and extract your product with a non water miscible solvent, the only other option is to remove the DMSO. Remeer the partition coefficient of the product in the non water miscible solvent must be higher than that of it for DMSO/water. Removal of DMSO is a pain in the arse, we do it on our rotovap occasionally.
DMSO is an effective pain killer, blocking nerve conduction fibers that produce pain. It reduces inflammation and swelling by reducing inflammatory chemicals. It improves blood supply to an area of injury by dilating blood vessels and increasing delivery of oxygen and by reducing blood platelet stickiness.

Jul 21, 2017· Connect vacuum pump to cold trap and cold trap to rotovap vacuum port. Turn on heat bath and set to 40°C (113°F). Once heat bath and coil have reached the desired temperature, turn on rotovap motor and set speed to approximately 100 RPM. Start vacuum pump and allow it to pull down for a few minutes before beginning injection.
The procedure is done at reduced pressure (either water aspirator, ~25 mm Hg, or vacuum pump (< 0.1 mm Hg) and the appliion of heat (water bath kinds of temperatures). There’s a nuer of tricks you can use, depending on the solubility of your compounds.

What is a rotovap? A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. A rotovap acts like a filter to separate the unwanted components in the extract as a final step to crude oil. The rotovap is a simple concept with a lot of moving parts.
