Rotavapor® R-100 Rotary Evaporators Standalone, BUCHI | VWR

The R-100 Rotavapor® is an entry level Rotavapor®, meeting the most essential needs in evaporation at BUCHI's unprecedented high quality standards.Rotary evaporators remove volatile solvents from nonvolatile reaction samples through evaporation. The overall solvent removal rate is increased by reducing the pressure and rotating for even heat application to surface area.

After 2 h the reaction mixture was warmed to room temperature and the solvent was removed on a rotovap. Hexane (100 mL) was added and the solution was extracted with water (50 mL), 20% NaHCO 3 (50 mL) and brine (50 mL). The hexane was dried over MgSO 4, filtered and the solvent was removed on a rotovap. The aliphatic thioesters were purified by .

degrees difference between the swing (at 40oC) and the boiling solvent. This will remove the solvent 6.5 times faster than at 2 mbar. If we can get down to 0.5mbar we can get the boiling point down to 18oC, which means 22 degrees difference, 11 times faster than at 2 mbar. The point here is clear.

In 2003 we used the following conditions: 100 degree for 3 min, then 10 deg/min up to 140 the starting 5-bromo-2-pentanone came out at approximately 1.9 min and the product at about 4.5 min. I'd probably try starting at a slightly lower temperature, maybe 80 degrees for 3 min and then ramp up at 20 deg/min to 160 degrees.
