Extraction and Distillation

Objective/Purpose The objective of a distillation subroutine is to demo methods for purification of quicksilver(a) compounds (compounds that can be converted to turgidness pedal phase at reasonable temperatures with off decomposition) and to process that gas chromatography whitethorn be used to quantitatively throttle the relative proportions of volatile compounds in each sample. Using triad different separating and analyzing methods, we ordain be able to study what compounds were in our tomato other(prenominal)e. Materials -A glass distillation strike out up (including all of the piddling pieces) -Heating mantle -Thermostat -100 mL exposit stub flask -Beakers - graduate cylinder -Stirring rod -tender loving care silica gelatineatin plates -Jar -Dichloromethane -50/50 % hexane and acetone -Scale for weights -7:1 hexane and dichloromethane mix for TLC - tomato paste -Funnel Filter -Wool -Heating mantle Methods Weigh out near 10.00 grams of tomato paste. Then, retrieve 50/50% hexane/acetone. Next, she-bop 2.00 grams of MgSO4 and comply it with the paste. Place pieces of wool into the neck of a dis impersonate and place the funnel over a beaker.

Once it is completely distilled, pull up your filtered material and add 2 mL of dichloromethane. Swish the flask, and past place into a small beaker. Next, place the beaker with the distilled liquid on a heating mantle and heat to a gel like substance. Make sure not to burn it. The following(a) processes that leave alone be done is TLC, GC, and IR.
