Simple Distillation and Gas Chromatography

Simple Distillation and burn step forward Chromatograpy In this experiment we register the methods for purification of volatile compounds and that muff chromatography may be don to quantitatively determine the comparative proportions of volatile compounds in all(prenominal) sample. To do this, we performed a simple distillment of a untested kind of Hexane-Heptane. We then self-contained ternion contrastive split ups from the distillation, enter the temperatures to severally(prenominal) one time. Then apply chromatograms, we comp ard the three fractions we obtained and determined the percentages of Hexane-Heptane for each fraction stack away. In a gas chromatogram, the bill areas are considered to be directly proportional to the amound of sample passing the demodulator in the gas chromatogram. The give in below shows the areas for each throwaway in each of our printed Chromatograms and the temperature at which we collected each fraction. sort out # anthesis #Area of Peak Temperature at which Fraction was collected 112353548.7429.9-37.7 degrees C 21No Peak Recorded38.6-39.9 degrees C 31153621.2639.9-49.2 degrees C 2 1431547.8239.9-49.2 degrees C left(p)field Over12896057.41Room Temperature These steers were taken with a Hexane-Heptane sort We can read some(prenominal) things from these results.

starting signal is that the largest area of a peak that we recorded was the material that was left oer from our distillation. This tells us that at that place was still a plentifulness of mixture that was not distilled. approximately likely, because Heptane has a higher change state point than Hexane, closely of the reply still left over that was recorded in the GC was Heptane. An separate thing that sticks out is that there was no peak recorded in our back up fraction. This could mean several different things. Because no peak was recorded, it leads us to believe that a grownup fraction was taken. Because this was the second fraction taken, there should be dickens peaks on the GC, one for Hexane and the other for Heptane. This is not the case. This could be...If you indirect asking to get a full essay, order it on our website: Ordercustompaper.com
