Diphosgene (ClCO2CCl3)
Diphosgene (Trichloromethyl chloroformate, ClCO2CCl3) is a chemical originally developed for chemical warfare, a few months after the first use of phosgene. At room temperature it is a stable colourless liquid. It decomposes to phosgene and chloroform at 300 °C.
Diphosgene can be used in the synthesis of isocyanates.
Diphosgene vapour is a lung irritant and has an LC100 for rabbits at a concentration of 0.9 mg/l of air.
Diphosgene was used as a poisonous gas in artillery shells by Germany during World War I. The first recorded battlefield use was in May of 1916. Diphosgene was developed because the vapours could destroy the filters in gas masks in use at the time.
