WebTo get vacuum below the melting point of the DMF you would need to reduce the pressure in the system to 2 microbar (10 -6 bar). I'm not sure that's feasable in a commercial system. WebLower boiling point solvents work best, but rotary evaporation is more commonly used to remove water (b.p. 100 ˚C). Higher boiling point solvents (DMF - b.p. 153 ˚C, DMSO, etc.) would be easier to remove using other techniques, but with the correct vacuum pump and conditions, higher boiling point solvents can be removed using rotary evaporation.
