Webcompound has a higher boiling point than the solvent. Lower 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 ... WebJun 12, 2013 · For temperature above 0 Kelvin and 273.15 Kelvin (0 Celsius) or below then water condensing from the atmosphere would form ice. For temperature between 0 Celsius and 100 Celsius liquid water would condense. Above 100 Celsius water wouldn't condense unless the gas phase of the system was under pressure.
