Simple Distillation and Gas Chromatography

Simple Distillation and Gas Chromatograpy In this experiment we evince the methods for purification of volatile compounds and that gas chromatography may be maintain to quantitatively determine the relative proportions of volatile compounds in all(prenominal) sample. To do this, we performed a simple distillation of a untested miscellany of Hexane-Heptane. We then self-contained three different dissevers from the distillation, enter the temperatures to to each one one time. Then using chromatograms, we comp ard the three fractions we obtained and determined the percentages of Hexane-Heptane for each fraction self-collected. In a gas chromatogram, the bill areas are considered to be directly proportional to the amound of sample passing the sensor in the gas chromatogram. The table below shows the areas for each steer in each of our printed Chromatograms and the temperature at which we collected each fraction. separate #Peak #Area of Peak Tempera ture 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 peaks were taken with a Hexane-Heptane sort We can read some(prenominal) things from these results.

set-back is that the largest area of a peak that we recorded was the material that was left everywhere from our distillation. This tells us that there was still a accord of mixture that was not distilled. Most likely, because Heptane has a higher turn point than Hexane, closely of the solution still left over that was re! corded in the GC was Heptane. Anformer(a) thing that sticks off 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 bad fraction was taken. Because this was the second fraction taken, there should be two peaks on the GC, one for Hexane and the other for Heptane. This is not the case. This could be...If you indirect request to get a luxuriant essay, order it on our website: OrderCustomPaper.com
