Week 9 Draft 1

During this experiment, cyclohexanol reacted with phosphoric acid under high temperature to perform the acid catalyst dehydration reaction and produced the target product of cyclohexene which was obtained in a 18.87% yield. The percent yield of 18.87% indicates 81.13% of the original amount was lost. A gas chromatography and infrared analysis readings were taken which illustrated data regarding retentions and peaks. In addition, two chemical tests were performed in a 3% solution of bromine in dichloromethane and 1% potassium permanganate and 10% sulfuric acid. These were known as the bromine in dichloromethane and potassium permanganate chemical tests. When performing the bromine in dichloromethane test for alkenes, the cyclohexene solution started out as clear and colorless and remained clear after the addition of bromine while cyclohexane started out as clear and colorless and turned to a color known as reddish-orange instantly when swirled. For the 1% potassium permanganate and 10% sulfuric acid test for alkenes, cyclohexane started out as a clear color and then turned into a brown precipitate. The cyclohexane started out as clear and converted into purple after the addition of KMnO₄.
