Simple Distillation and Gas Chromatography

Simple Distillation and Gas Chromatograpy In this experiment we gift the methods for purification of volatile compounds and that gas chromatography may be take for to quantitatively determine the relative proportions of volatile compounds in all(prenominal) sample. To do this, we performed a simple distillation of a untested mixing of Hexane-Heptane. We then self-contained three different reckons from the distillation, enter the temperatures to severally one time. Then using chromatograms, we comp ard the three fractions we obtained and determined the percentages of Hexane-Heptane for apiece fraction tranquil. In a gas chromatogram, the bill atomic number 18as are considered to be directly proportional to the amound of sample passing the demodulator in the gas chromatogram. The table below shows the areas for each aggrandisement in each of our printed Chromatograms and the temperature at which we collected each fraction. split up #Peak #Area o f 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 wingfield Over12896057.41Room Temperature These peaks were taken with a Hexane-Heptane sort We can read some(prenominal) things from these results.

number one is that the largest area of a peak that we recorded was the material that was left all over from our distillation. This tells us that there was still a bundle 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 recorded in the GC was Heptane. An new(prenominal) thing that sticks step to the fore is that there was no peak recorded in our irregular 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 generous essay, order it on our website: OrderCustomPaper.com
