9. Once a steady evaporation rate is reached the solvent sample can be left to evaporate to dryness. If the sample required is volatile, then it should be removed before this point to ensure no loss of product. When the solvent has all evaporated follow these steps to shut down the rotary evaporators. 1. Raise flask out of the water bath. 2.

It can also be seen from the graph that for toluene the vapor pressure equals atmospheric pressure at a temperature of 111 C. The BP of toluene is therefore 111 C. Note that at any given temperature the vapor pressure of cyclohexane is greater than the vapor pressure of toluene. Consider next the behavior of a mixture of two liquid compounds.

Mar 31, 2018 Substances with an evaporation rate of 3.0 (three times the evaporation of normal butyl acetate), such as acetone (5.6), hexane (8.3), or methyl ethyl ketone or MEK (3.8), are known as fast evaporating. Substances with an evaporation rate between 0.8 and 3.0, such as ethyl alcohol (1.4) or VMP naphtha (1.4), are known as medium evaporating.

The RotoVap Limitations. For years, the industry standard for solvent recovery has been the rotary evaporator, or otherwise known as the RotoVap. A generic 20L RotoVap has a recovery rate of about 1.5 gallons per hour. For small-scale setups, this may suffice, but large-scale manufacturers have been forced to run multiple RotoVaps.
