How do organic chemists remove solvents with high boiling .

If you are fortunate to want to remove the solvent from something that is non-volatile and not too heat sensitive, the common approach is to use a rotovap to strip off the solvent. The procedure is done at reduced pressure (either water aspirator, ~25 mm Hg, or vacuum pump (< 0.1 mm Hg) and the application of heat (water bath kinds of .

Recrystallization (Advantages) - Chemistry LibreTexts

The ideal solvent should boil higher than, say, DCM or ether, but you can use solubility in the low-boiling stuff to point you in the direction of something more appropriate. If DCM seems like it may work, try recrystallizing in 1,2-dichloroethane. If pentane (or hexane or pet ether) looks good, use heptane. Set up.

Dec 08, 2016 · The oil was then dissolved in refluxing hexane (3 mL, ~1 mL/g) and the solution was allowed to cool to room temperature then placed in the freezer. The resulting white solids were collected by vacuum filtration, washed three times with cold hexane, and dried by rotovap (0.58 g crude product). HPLC indicated 92.2% purity.

Rotary Evaporators - Across International

A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. Rotary evaporation is most often and conveniently applied to separate "low boiling" solvents such a n-hexane or ethyl acetate from compounds which are solid at room temperature and pressure.

We are using a rotovap to evaporate hexane from a solution .

The goal of a rotovap is to heat the liquid, and apply a vacuum, to lower the boiling point and get the liquid out. At 25 degrees F, the vapor pressure of hexane is approximately 35 mmHg.
