Chloroform, or Trichlormethane (CHCI3), is prepared on a commercial scale by treating a pure acetone with chlorinated lime. Usually, less than 1% of alcohol is added to prevent decomposition. Chloroform should be kept in well-stoppered bottles, in a cool place, and well protected from light. It should never be used near an open flame, lest irritating decomposition vapors be developed.

Evaporate some Chloroform from filter paper laid on a warm glass plate. When Chloroform is completely evaporated, note if filter paper has any foreign odor..............................................................................................................................................................................................................................................

The principal use for Chloroform is for the production of general anaesthesia.

Official preparations are: Aqua Chloroformi, Linimentum Chloroformi, Spiritus Chloroformi.
