Explanation / Answer
Reaction
1)Take a 50mL round bottom (RB) flask.
2)Accuately weigh 150mmol of 2-methylcyclohexanol or 4-methylcyclohexanol(cis-trans mixtures)and add it into the RB flask.
3)Then add 5mL of 85% phosphoric acid into it add some glass beads or boiling chips into it.(We are adding glass beads or boiling chips to avoid bumping while heating.)
4)Clamp the RB flask to a ring stand over a suitable heat source and assemble an apparatus for simple distillation.
5)Use a 10mL graduated cylinder or another graduated container as the reciever during the distillation process.
6)Keep ready two clean,numbered 15mL screw cap centrifuge tubes.
7)If you are using a sirrer means start it,and then heat the reactants.(the product mixture distills at a rate of 1 drop per second or less.
8)Once the distillation begins record the vapour temperature and keep recording the temperature at intervals during the reaction.
9)Monitor the volume of the alkene(top) layer in the distillate.
10)When the alkene volume is about 8mL quickly pour it into the first centrifuge tube,cap the tube.
11)Replace the graduated reciever and continue distilling.
12)After the alkene volume reaches about 6mL,monitor the still-head temperature continually.Lower the heat source and turn it off.
13)When you observe a marked drop at the still head ,which may be accompanied by foaming and dense white fumes in the RB flask,then pour the distillate into the second centrifuge tube and cap the tube.
Separation
1)for each separate fraction,we want to do the following process
wash op[24]each distillate with 5mL of saturated aqueous bicarbonate and remove the aqueous layer(lower) with a pasteur pipette, repeate the process once again.collect the top layer(you should do this step for both distillate fractions.
2)Dry each alkene [op-25] mixture separately in the centrifuge tube with anhydrous calcium chloride or any other suitable drying agent.
3)Centrifuge it[op-17],if necessary.
4)Collect the liquid into a labeled,tared screw cap vial.
5)Measure the mass of each alkene fraction and calculate the total mass of alkenes.
Analysis
1)Analyze both fractions by gas chromatography[op-37]
2)Measure the area and retension time of each peak on your gas chromatography.
3)Identify the peaks by comparison with a chromatogram provided by your instructor or by spiking your product mixture with an authentic sample of 1-methylcyclohexane and obtaining a chromatogram of the resulting mixture.
4)Assuming that the detector response factors for the alkenes are equal,calculate the percentage composition of each fraction.
