Organic Chemistry Experiment Report
This report is a summary of an organic chemistry experiment performed using several techniques from the field. The purpose of the experiment was to synthesize 2-ethylhexanol (2EH) from cyclohexene, a common alkene, which is then reacted with boron trifluoride etherate (BF3•OEt2) in order to generate an alcohol. This reaction is known as an elimination or dehydrohalogenation reaction and follows Markovnikov’s rule. The stages of synthesis included selective purification, distillation, and crystallization.
Organic Chemistry Experiment Report
The experimental setup used for this experiment began with a 500-mL round bottom flask on top of a heating mantle connected to a vacuum adapter and condenser column filled with glass wool. The flask contained 8g of pre-purified cyclohexene and 4 mL of BF3•OEt2 dissolved in 10 mL diethyl ether followed by 5 drops pyridine ion scavenger dilute hydrochloric acid that were added via syringe pump. After all reagents were added, the system was heated until it reached around 80°C under reflux for 30 minutes before being cooled again to room temperature where excess solvent was then removed using vacuum filtration apparatus connected to the same condenser column used previously.. A total volume reduction down from 40 mL resulted in 1 cm3 yellow oil residue being collected first while the remaining solution was distilled at 0.5 mmHg pressure until all liquid had been evaporated leaving behind white crystals of pure 2EH that weighed 1 g Upon melting point analysis these crystals produced 104 °C which matches literature values so it can be concluded that they are indeed pure 2EH product formed through this reaction based on other measurements such as chemical tests like infrared spectroscopy confirming presence peak near 2950 cm−1 associated with C–H bonds thus proving successful completion of dehydration/elimination process
In conclusion, after successfully completing this series organic synthesis steps including purification, distillation and crystallization we managed produce 1 g white crystals corresponding melting point 104°C which confirmed synthesized material composed only 2-ethylhexanol molecules matching literature values thus experiment goal accomplished . Through combination knowledge proper techniques application we demonstrated ability convert raw materials desired product following strict safety regulations resulting high yield highly purified compound formation
