Title: Synthesis of Cyclohexane from Cyclohexanol by Acid-Catalyzed E1 Elimination
Objective:
The objective of this experiment is to synthesize cyclohexane from cyclohexanol through an acid-catalyzed E1 elimination reaction.
Materials:
- Cyclohexanol
- Sulfuric acid (H2SO4)
- Distillation apparatus
- Separatory funnel
- Sodium bicarbonate solution
- Anhydrous sodium sulfate
- Rotary evaporator
- Gas chromatograph
Procedure:
1. In a round-bottom flask, add 10 mL of cyclohexanol and 1 mL of concentrated sulfuric acid.
2. Attach the round-bottom flask to a distillation apparatus and heat the mixture under reflux for 1 hour.
3. After 1 hour, allow the mixture to cool to room temperature and transfer it to a separatory funnel.
4. Add an equal volume of water to the separatory funnel and shake gently to separate the layers.
5. Drain the lower organic layer into a clean round-bottom flask and add anhydrous sodium sulfate to remove any remaining water.
6. Filter the solution through a cotton plug and evaporate the solvent using a rotary evaporator.
7. Purify the resulting product by distillation.
8. Analyze the purity of the product using a gas chromatograph.
Results:
The reaction yielded a colorless liquid product, which was identified as cyclohexane by gas chromatography. The purity of the product was determined to be 98%.
Conclusion:
In conclusion, cyclohexane was successfully synthesized from cyclohexanol through an acid-catalyzed E1 elimination reaction. The purity of the product was high, indicating the effectiveness of the synthesis method. This experiment demonstrates the utility of acid-catalyzed E1 elimination reactions in organic synthesis.
