4-Methylcyclohexanol Reaction Lab Report
In order to first perform the reaction, 1.5 mL of 4-methylcyclohexanol was added to a pre-weighed 5mL conical vial. The conical vial was then weighed to find the actual mass of 4-methylcycloheaxanol. Then, 0.4mL of 85% phosphoric acid was added to the conical vial using a plastic pipet. Six drops of concentrated sulfuric acid was then added to the vial using a glass pipet. A spin vane was then added before adding the Hickman head, water condenser and a drying tube packed with calcium chloride to the conical vial. The apparatus was then placed onto an aluminum block on a hot plate. The hot plate was then heated to approximately 170 Degree Celsius. The distillate was then removed from the Hickman head as it formed and added to a 3 mL conical
vial. The conical vial was then sealed using a screw cap and rubber septum. The conical vial was also wrapped with aluminum foil. The reaction was allowed to proceed for approximately 30 minutes. Once the distillate had stopped forming, it was removed from the aluminum block and allowed to cool down before disassembling it. In order to purify the distillate, 1.2 mL of saturated sodium chloride was added to the 3mL conical vial with the crude product and tightly capped. The layers were then allowed to separate by shaking the vial rigorously. The bottom aqueous layer was then transferred into a clean test tube. Then, anhydrous sodium sulfate was added to the conical vial and allowed to sit for a few minutes. The organic layer was then separated using decantation onto a pre-weighed test tube and the final weight was recorded. A liquid reflectance infrared spectrum of both the final product and the initial reagent. 4 drops of the product and 4 drops of the reactant were then added to two dry test tubes. Two drops of molecular bromine were then added to each test tube and the color change was recorded.
