Apr 01, 2010 The flask with the solution is placed on the rotary evaporator. The use of a bump trap prevents the solution from accidentally splashing into the condenser (and being contaminated). It is highly advisable to start with a clean bump bulb in case something bumps over after all! This would allow the experimenter to recover the solution or solid. 3.

How does rotary evaporation work? -

How does the rotary evaporator work? The rotovap works by increasing the rate of evaporation of the solvent by (1) reducing the pressure to lower the solvent boiling point, (2) rotating the sample to increase the effective surface area and (3) heating the solution. To use the rotovap, first make sure that the power is on (top right of the stand).

Jul 01, 2015 Hence, distillation was employed to separate toluene from DES/toluene mixtures. In this experiment, a rotary evaporator was used to separate toluene from DES/toluene mixtures at 100 C. The extraction of toluene from toluene/n-hexane mixtures with 45% toluene was performed at 30 C. Then DES was regenerated by evaporation.

remove the methanol using rotary evaporation. Cool the flask to room temperature and add 13 g of 2-HMP and 200 mL of toluene to the flask. Swirl the mixture and then allow it to stand for an hour. Remove the toluene using rotary evaporation. Seal the flask and allow the coated adsorbent to stand overnight at ambient temperature.

Using our in-line evaporator therefore, a 0.16 mL min−1 flow of a toluene solution of 1 was conveniently combined with 0.64 mL min−1 MeOH at a T-piece. The 1:4 mixture of toluene and MeOH was then passed through the evaporator at 20 C, with a gas flow rate of 10 L min−1, such that toluene was removed at a faster rate than MeOH. The ...

solvents - What is the best way to evaporate toluene?

Well if your product were a volatile liquid, than toluene's 110 ∘ C boiling temperature (of the pure solvent at atmospheric pressure) may be dangerously high. If you aim for a solid of low volatility, evaporate it under the reduced pressure of a membrane pump and gentle warming by a water bath. If accessible, a rotary evaporator is a good thing for this: lower the pressure gradually …
