Properties[change | change source]
It is a colorless liquid. It smells like ether. It evaporates quite quickly. It can dissolve fats and oils as well as other stuff such as iodine. It doesn't burn, but it does make phosgene when heated to a high temperature.
Preparation[change | change source]
It is made by reacting methane with chlorine. This reaction is similar to the burning of methane (reaction of methane with oxygen). Hydrogen chloride is a byproduct (left over substance). It used to be made by reacting carbon disulfide with chlorine. This reaction would produce sulfur(I) chloride.
Uses[change | change source]
The uses of carbon tetrachloride have diminished lately because it is known to be damage people's health. People think it might damage the ozone layer. Today, it is rarely used for anything.
