Fractional distillation is a more viable technique than straightforward distillation because fewer material is lost throughout the procedure. Therefore, the distilled compounds are more purified in the results. The copper wire in the fractionating column acts to copy multiple distillations in one round of fractional distillation.
During fractional distillation of unknown 20, I observed a higher boiling compound at about 79 degrees celsius and a lower boiling compound at about 56 degrees celsius. There was a 1:1 ratio of higher and lower boiling points from the product collected in the vials. It can be determined that the lower boiling point compound is acetone because acetone boiling point is 56 degrees celsius. Moreover, the identification of the higher boiling point compound is 2-methyl-2-propanol. The theoretical boiling point for 2-methyl-2-propanol is 82 degrees celsius, which is about 3 degrees different from the experimental boiling point. The difference could be due to human error by heating the compound too quickly. The experimental results for this procedure are accurate because fractional distillation provide pure compounds that are less likely to be lost during the process.

You link your first two sentences using the word "therefore," yet they do not seem to have anything to do with eachother. I'm unclear as to how losing fewer materials during the procedure leads to a more pure product.

You may incorporate the first paragraph into the second, but there is an emphasis on the results of the experiment. Your paragraph may be stronger if you just focused on the second paragraph and discussed the results.
