Fractional distillation lab conclusion

good introduction paragraphs for essays

Distillation probably accounts for 90% of all separation processes in the chemical industry and is also distullation significant user of energy due to the necessary heating involved. James 5 Conclusion: From the chart it appears that the fractional distillation was slightly more efficient than the simple distillation. The simple distillation graphed basically as a straight line, but the graph of the fractional distillation actually, to a certain degree, shows a plateau. This plateaThe purpose of this laboratory experiment was to fractionally distill waste acetone from last semester using a self-prepared apparatus in order to purify it back into pure acetone, as well as to learn how to use a refractometer to obtain a refractive index of our purified acetone and compare that value to a literature value to determine if the compound was indeed acetone.

An experimental flaw could have been that the waste acetone had compounds in it that lowered the boiling point of the mixture, resulting in a lower boiling point. Another reason could be the differenIn conclusion to the distillation lab, Coclusion think our data shows fractional distillation lab conclusion our experiment went xistillation. Our graph resembles the graph in the lab handout (graphs attached to lab notebook sheets). The fractional distillation shows the sharp slope between when the cyclohexane burns off and mostly only toluene remains.

The microscale graph seems to be accurate because it shows the large jump where the cyclohexane is burned distillatin. To view the apparatuses used in the experiment look at the attached pictures. To compare the simple and fractional distillation, our GC analysis shows the samples we submitted. The first samples of our simple distillation showed that 7.21 percent of the mixture was composed of cyclohexane and 23.3 percent was toluene. The first few drops of our fractional distillation had cyclohexane composing 70.5 percent of the mixture leaving 29.27 percent for toluene.

Discussion and Fractional distillation lab conclusion This experiment was meant to demonstrate how a mixture of two different components with different vapor pressures can be separated fractional distillation lab conclusion fractional distillation. The theory behind fractional distillation is dependent on the idea that at every given temperature of the mixture, the.
