How to make chloroform?
<|assistant|>
Chloroform can be made by mixing chlorine with an organic compound such as ethanol in the presence of a catalyst. The reaction usually takes place over several days and can be conducted in several stages. The first stage involves treating sodium or potassium chloride with sodium or potassium bi-carbonate in the presence of ethanol. The resulting solution is then concentrated in a vacuum to form chloroform. The process can be monitored using chemical tests to identify the products formed, and reactions can be speeded up using various techniques.
