Simple Distillation and Gas Chromatography

Simple Distillation and gas pedal Chromatograpy In this experiment we lay break the methods for purification of volatile compounds and that gas chromatography may be slang to quantitatively determine the telling proportions of volatile compounds in all(prenominal) sample. To do this, we performed a simple distillate of a untested florilegium of Hexane-Heptane. We then self-contained three dissimilar divides from the distillation, enter the temperatures to to apiece one one time. Then exploitation chromatograms, we comp ard the three fractions we obtained and determined the percentages of Hexane-Heptane for each fraction undisturbed. In a gas chromatogram, the bill beas are considered to be directly comparative to the amound of sample passing the sensor in the gas chromatogram. The table below shows the areas for each efflorescence in each of our printed Chromatograms and the temperature at which we collected each fraction. secern # bank bill #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 oddfield Over12896057.41Room Temperature These cards were taken with a Hexane-Heptane word form We can read some(prenominal) things from these results.

initiative is that the largest area of a circular that we recorded was the material that was left oer from our distillation. This tells us that at that place was still a group of mixture that was not distilled. close to likely, because Heptane has a higher change state point than Hexane, closely of the issue still left over that was recorded in the GC was Heptane. An another(prenominal) thing that sticks out is that there was no peak recorded in our bet on fraction. This could mean several different things. Because no peak was recorded, it leads us to believe that a vainglorious fraction was taken. Because this was the second fraction taken, there should be devil peaks on the GC, one for Hexane and the other for Heptane. This is not the case. This could be...If you indirect invite to get a upright essay, order it on our website: Ordercustompaper.com
