In the fume hood, turn on the sand bath onto 40. In a small 10 ml round-bottomed flask add about 2 grams of cycloexanol (2.013 g used). Then add to the same flask 85% phosphoric acid (0.5 mL) and boiling chips. Using the distillation setup, distill the reagents into a collection vial at the rate of 20 to 30 seconds per drop. At the first drop write down the temperature ( 66^oC), and stop distillation when there is only 10% of liquid left in the flask. In the collection vial there will be two layers (water and cyclohexene). Using a pipet, the contents of the collection vial are transferred into a test tube. Then add about 1 ml of distilled water into the test tube. After remove the lower aqueous layer via pipet. After, add 1 mL of 1 M sodium hydroxide (NaOH), and again remove the lower aqueous layer. Add 1-2 ml of saturated aqueous sodium chloride, brine, to the test tube. For the third time remove the lower aqueous layer. The organic layer is left in the test tube, transfer the layer into a new vial. After, add CaCl₂ to the new vial until the CaCl₂ does not clump together. The vial should be capped and left to dry for at least five minutes. After the drying process, transfer the product into a new tared vial. The weight of the product was .722 g. Then calculate the percent yield, which was 35.9 %.
