Synthesis
Chlorination of iodoform with phosphorus pentachloride leads to carbon tetrachloride via a chlorotriiodomethane intermediate.[4]
It can also be obtained by distilling trichloroacetyl chloride and hydrogen iodide at 140 °C, with hexachloroethane as a byproduct. Trichloromethane or carbon tetrachloride can also be reacted with iodine and sodium hydroxide at 0 °C to obtain the compound, but the yield is very low.[5]
