Brittney Brown Due: 10-22-2009 Title: The Preparation of Cyclohexanol from Cyclohexanone Lab Partner: Chelsea Searels The purpose of this lab was to prepare the alcohol cyclohexanol from cyclohexanone using sodium borohydride, which is an efficient reducing agent for ketones (1). An experimental infrared spectroscopy was obtained of the product and compared to the actual infrared spectroscopy of cyclohexanol to confirm it was the desired product. Experimental Details: Table 1. List of Reagents/Reactants Substance Amount (g) Molecular Weight (g/mol) Mmol Density (g/ mL) Boiling Point (°C) Cyclohexanone 5.2mL 98.1 50 0.948 155-165 NaBH 4 0.993 37.8 26.4 1.07 36 Methanol 25mL 32.04 --- 32.04 64.7 HCl 10mL 36.46 --- 1.8 110 Ether 25 mL (twice) 74.12 --- 0.7134 34.6 Sodium sulfate Until dry --- --- --- --- Ice water 50 mL --- --- --- --- Cyclohexanol (Product) 2.536 100.16 50 0.926 161 First, 1.0g of NaBH4 was added slowly to 5.2mL of cyclohexanone. The solution was allowed to sit for 11 minutes before added 10mL of 5% HCl and 50mL of ice water. After 5
