Lab Report Summer, 2002 Title: Distillation Purpose: The Purpose of this experiment was to test the theory of Simple vs. Fractional Distillation using cyclohexane and toluene. Cyclohexane: B.P. 80.7 ºC Toluene: B.P. 110.6 ºC Procedure: 20 ml of Cyclohexane and 20 ml of Toluene were placed in a 100 ml round bottom flask. The contents were swirled to mix and a boiling rock was added. The Simple Distillation apparatus was setup using technique 7.3. A 50 ml graduated cylinder was used …showed first 75 words of 251 total…

The data gathered from simple distillation follows the the theory but the data shared from another group for farctional distillation did not prove the theory of simple vs. fractional distillation theory. In the data for the Fractional distillation, there was no real sudden rise in the temperatures.
