Triphosgene is a potent toxin that forms colorless crystals.

Production and representation

Triphosgene can be obtained by chlorination of dimethyl carbonate.

Properties

The compound decomposes on boiling partially with the release of phosgene and Diphosgene. Chemically behaves triphosgene similar to these substances, however, all reactions proceed more slowly. In the 1930s, this compound has been discussed yet as a potential chemical warfare agent. Its present meaning is rather low. It is taken up through the respiratory tract and causes pulmonary edema -like symptoms such as cough, nausea, shortness of breath and vomiting. Later in pulmonary embolism or myocardial infarction may occur. Your eyes will also be attacked, so after contamination immediate flushing of the eyes is necessary.

Use

As a synthesis chemical solid triphosgene in solvents can often replace the highly toxic gas phosgene. Triphosgene is used for the production of B Octalactin.
