Simple Distillation and Gas Chromatography

Simple Distillation and Gas Chromatograpy In this experiment we parade the methods for purification of volatile compounds and that gas chromatography may be r individually to quantitatively determine the relative proportions of volatile compounds in all(prenominal) sample. To do this, we performed a simple distillation of a untested commixture of Hexane-Heptane. We then self-contained three different segments from the distillation, enter the temperatures to each one time. Then using chromatograms, we comp ard the three fractions we obtained and determined the percentages of Hexane-Heptane for each fraction accumulate. In a gas chromatogram, the bill areas are considered to be directly proportional to the amound of sample passing the sensing element in the gas chromatogram. The table below shows the areas for each wind in each of our printed Chromatograms and the temperature at which we collected each fraction. disarticulate #Peak #Area of Peak T emperature 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 unexpendedfield Over12896057.41Room Temperature These peaks were taken with a Hexane-Heptane sort We can read some(prenominal) things from these results.

graduation exercise 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 pass around of mixture that was not distilled. Most likely, because Heptane has a higher stewing p oint than Hexane, closely of the solution s! till left over that was recorded in the GC was Heptane. An early(a) thing that sticks stunned is that there was no peak recorded in our succor 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 blanket(a) essay, order it on our website: OrderCustomPaper.com
