Distillation Lab Report

Despite a slight deterioration in temperature between 12 milliliters and 13 milliliters of distillates collected, Figure 1 roughly resembles the reference fractional distillation plot.1 While the amount of distillates for Fraction 1 and Fraction 2 appears to be similar in the reference plot, Figure 1 displays a larger volume for Distillate 1 as compared to Distillate 3 in terms of relative length of periods at constant temperature. Additionally, the slope for Fraction 2 on the reference plot is very steep, but the slope for Distillate 2 varies from a similar slope to Distillate 1 that later becomes almost as steep as the reference slope. This is due to the fractional column not having enough theoretical plates to handle the separation, so the mixture distilled until all of the lower boiling point component, cyclohexane, was removed. The slope of Figure 1 between 13 milliliters to 16 milliliters of distillates collected is also flatter in comparisons with the

In Figure 1, Distillate 1 appears constant with a slight increase between 76 ° C to 78 ° C. As a result, 12.381 % of the gas chromatography evaluation of Fraction 1 was toluene. For the gas chromatography results of Fraction 2, in which Figure 1 shows the temperature continuously increases; that denotes that there was a mixture of two components. As a result, 75.912% of the sample obtained was cyclohexane, and the rest was toluene. If the collection of Distillate 2 was taken earlier, the amount of toluene would be closer to the amount of cyclohexane. For Distillate 3, the temperature appears constant in Figure 1. This was the boiling point plateau for the higher boiling component, toluene. As a result, only 0.4300% of the gas chromatography results for Fraction 3 was cyclohexane, and the rest were
