Unformatted text preview: Wong, Benny Simple and Fractional Distillation Lab # 1 Purpose The aim of the experiment is to separate a mixture of two miscible liquids with different boiling points. Table 1: Physical Properties and Hazards of Chemicals used Molecular Formula Molecular Weight (g/ mol) Boiling Point (C) Melting Point Density (g/cm 3) Ill Effects Water H 2 O 18.02 100 1.00 None Methanol CH 3 OH 32.04 64.7 97 0.792 Can cause blindness Procedure For the simple distillation experiment, use a 50:50 (by volume) mixture of methanol and water. Afterwards, add boiling chips to the solution. Attach the distillation head to the boiling flask and secure the two with the three-finger clamp. Place a thermometer into the top tube of the distillation head. The solution is heated using a heating mantel and cooled via a shortpath distillation head. Remember to attach the input hose into the second head and attach the exhaust hose into the first head. The supply of heat must be sufficient to allow the liquid to distill at a hose into the first head....
