The vapor rises from the distillation flask and touches the thermometer, which records the vapor temperature. The first graph will be a determination of temperature vs fraction number(or volume); the second graph will be an analysis of composition of each component versus fraction number (a total of four graphs). 0000001744 00000 n
The laboratory distillation column can be operated at finite reflux for 2.9 hours considering an actual reflux ratio of 8.357 and a boilup ratio of 0.4387. Theresultant thermometer was placed through the adapter and pushed beside the opening of the Ryan Huckaby In fractional distillation, the area percent of 2-methylpentane was 80.464% and 19.536% cyclohexane. For the simple distillation experiment, save a late higher-boiling 5 mL fraction for GC analysis in a labeled vial. In this experiment, you will be conducting both a simple distillation and a fractional distillation of a mixture of cyclohexane (bp=79) and methylcyclohexane (bp=101) to compare the two techniques. The vapor then goes through the condenser where it is liquefied by cold circulating water. The column will operate at temperatures ranging from 0-100oC.
