Extraction and Distillation

Objective/Purpose
The objective of a distillation process is to demo methods for purification of quicksilver(a) compounds (compounds that can be converted to gas pedal phase at reasonable temperatures with off decomposition) and to demonstrate that gas chromatography whitethorn be used to quantitatively determine the relative proportions of volatile compounds in each sample. Using three different separating and analyzing methods, we ordain be able to study what compounds were in our tomato paste.
Materials
-A glass distillation strike out up (including all of the piddling pieces)
-Heating mantle
-Thermostat
-100 mL exposit bottom flask
-Beakers
- graduate cylinder
-Stirring rod
-TLC 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 approximately 10.00 grams of tomato paste. Then, retrieve 50/50% hexane/acetone. Next, she-bop 2.00 grams of MgSO4 and combine it with the paste. Place pieces of wool into the neck of a displace and place the funnel over a beaker. Mix 15 mL of 50/50% into the beaker, stirring to get a liquid from the paste. Then, pour just the liquid into the funnel to slabber it out.



Do this one more time the exact same, and because a third time using only 10 mL of the mixture. Each of the three times you do this, bring up the liquid. Transfer the liquid into the large 100 mL round bottomed flask that is connected to your simple distillation set up. Distill the tomato paste liquid. 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 will be done is TLC, GC, and IR.
