Chloroform, also known as trichloromethane, can be prepared by the reaction of acetone with sodium hypochlorite (bleach) in the presence of a base such as sodium hydroxide. Here is a general outline of the preparation process:
1. Mix acetone with sodium hypochlorite (bleach) in a reaction vessel. 2. Add a base, such as sodium hydroxide, to the mixture to catalyze the reaction. 3. Allow the reaction to proceed, typically at room temperature or slightly elevated temperatures. 4. Chloroform will form as a byproduct of the reaction and can be separated from the reaction mixture by distillation.
It is important to note that chloroform is a hazardous chemical and should only be prepared and handled by individuals with proper training and safety equipment. Additionally, the production and use of chloroform are regulated in many countries due to its toxicity and potential health risks.
