Trichloromethanesulfenyl chloride is a highly toxic chemical compound with the molecular formula CCl 4 S.
Presentation and extraction
The compound can be prepared from the reaction of carbon disulfide with molecular chlorine in the presence of iodine or hydrogen chloride . Further synthesis possibilities exist in the chlorination of dimethyl sulfide or of thiophosgene .
properties
Trichloromethanesulfenyl chloride is a foul smelling, toxic liquid that boils at 147–149 ° C. In benzene it has a dipole moment of 0.65 D .
use
The substance can be used for the synthesis of thiophosgene . For this purpose, it is with iron (III) chloride - catalyst at 140 ° C in xylene implemented.
Trichloromethanesulfenyl chloride was used under the code name " Clairsite " by French and Russian armed forces as a chemical warfare agent during the First World War .
The dichlorofluoromethylsulfenyl chloride , which is required for the production of the fungicides dichlofluanid and tolylfluanid , can be obtained through a chlorine-fluorine exchange using mercury (II) fluoride or silver (I) fluoride .
safety instructions
Trichloromethanesulfenyl chloride can be absorbed through the respiratory tract, dermally or orally. It irritates the eyes, throat, bronchi and alveoli. It causes liver and kidney damage in the human organism. Animal experiments with rats and mice showed high inhalation and oral toxicity with symptoms such as diarrhea, skin irritation and changes, and dyspnoea.
