Synthesis of chloroform

Preparation of chloroform

Preparation of trichloromethane (chloroform)

Preparation of chloroform (chloroform)

200 g of fresh bleaching powder are ground up to a thin paste with 800 ml of water. The mixture is transferred to a large flask fitted with a distillation condenser and receiving flask. 40 g of acetone or ethanol are then added and the reaction mixture is cautiously heated until the reaction sets in. Th chloroform is removed by distillation and the distillate is washed with dilute solution of sodium hydroxide, dried over calcium chloride, and then redistilled. Chloroform is a heavy colorless liquid with a sweet smell boiling point 61° C. Yield about 40 g.

Preparation of chloroform is presented in the following video by Doug’s Lab.

Preparation of chloroform by electrolytic process

A 20 % solution of sodium chloride is heated at 100° C and is stirred. As anode a carbon spatulas is used and 5-6 amp. current is passed. Acetone through the pipe is introduced into the bottom of the flask and is acted upon by the chlorine, forming a compound intermediate chlorinated compound which is decomposed by the action of the sodium hydroxide produced, giving chloroform. The yield of chloroform is 85 % of the theoretical.

    2-propanol may also be used insted of acetone in the first procedure. For this, a larger amount of the hypochlorite is required as the 2-propanol is first oxidized to 2-propanone.
