Sulfuric Acid Analysis

Analysis:

In this experiment sulfuric acid, water, and cyclohexene are combined to integrate a product. This was sent through distillation which then created the reaction product of Cyclohexanol. After this distillation, the cyclohexanol still included hydrogen sulfate and other unreacted materials. To remove the remaining impurities, more distillations and the adding of NaCl and ether were performed. The synthesis of Cyclohexanol from Cyclohexene is an example of hydration reaction.
There were numerous impurities distilled and collected before we reached the final product. at 71o C, the cyclohexene water azeotrope was expected to distill, but because none did, its said to be that all the cyclohexene was used up in the reaction. At 980 C, the cyclohexanol water azeotrope is to distill into another flask. The first drop (low refraction) was at 97.2o C.   at 162o C, the boiling point for Cyclohexanol, is the only substance that is left in the reaction flask. To determine its identity and purity, the Cyclohexanol is subject to more tests.
A refractometer is a laboratory apparatus for measuring the refractive index of a substance like water or alcohol. In general, refractometers are utilized to determine the composition and purity of substances quantitatively. (eHow.com). In this case, it was used to determine the purity of the Cyclohexanol. The lit refractive index of Cyclohexanol is 1.46 ND T at 20o C. The experimental product that came out was 1.3953 NDT at 20.3o C. The corrected value at 20o C was 1.395435 NDT. The difference was .064565 NDT. Because the corrected value was not within .002 NDT of the lit refractive index, the cyclohexanol is a technical grade purity.
The infrared spectroscopy reveal the structures of covalently bonded chemical compounds such as organic compounds. (eHow.com). For this experiment we used the IR spectroscopy to further confirm the identity to be Cyclohexanol. All the peaks given accommodate for the match of cyclohexanol. The...
