![EXPERIMENT 2B
PREPARATION OF ETHYLENE
MATERIALS AND REAGENTS
95% Ethanol
Distilling flask
Sulfuric acid, concentrated
Rubber tubing
Sodium carbonate, 10% solution
Test tubes
Potassium permanganate, 1% solution
Test tube holder and rack
Bromine, 0.5% solution in carbon tetrachloride
PROCEDURE
1. Pour 10 mL of ethyl alcohol into the flask.
2. Add gradually with constant shaking 30 ml of conc. H;SO4.
3. Transfer the solution into the distilling flask.
4. Arrange the apparatus as shown. Collecting through should contain 10% Na;Co; solution. Have
the instructor check your set-up before heating.
