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.

Jul 08, 2021 Rotovap is a device for quickly concentrating liquid samples. The liquid sample is heated and decompressed in a spherical glass container, and continuously rotated to increase the evaporation surface area and accelerate the evaporation rate. Rotating evaporators are often used with water circulation vacuum pump.
