Chloroform is a good extraction solvent for some organics. It can be prepared from bleaching powder that contains Cl2(s) and acetone.

Make 5g of fresh bleaching powder into a smooth paste with 10mL of water and transfer it to a small bottle. Add 2mL of acetone in small portions with a dropper shaking after each addition and cooling if necessary. Carefully distill mixture until oily drops cease to pass over. Transfer distillate to separatory funnel and wash with a medium concentrated solution of baking soda and then with water(if available dry solution with anhydrous magnesium sulfate). Redistil and collect the fraction between 60 - 62C. (Chloroform is denser than water so when doing liquid-liquid extraction the organic chloroform layer will be below the aqueous layer.
