The description of Triphosgene

Triphosgene bis(trichloromethyl) carbonate, is a stable,crystalline solid which has accepted to be a advantageous acting for phosgene. It is safer and added acceptable to handle, transport and store. Exact amounts may be advised calmly and acclimated to perform adapted actinic transformations. Acknowledgment requires only one-third agnate of triphosgene in a lot of cases. Triphosgene can be calmly recrystallized from baking hexanes to crop authentic white crystals. The toxicity of triphosgene is the aforementioned as phosgene back it decomposes to phosgene on heating and aloft acknowledgment with nucleophiles. Even trace damp leads to accumulation of phosgene. Therefore this reagent can be cautiously handled if one takes all the precautions as for phosgene. Anything beneath may aftereffect in a alarming situation.Triphosgene (Bis(trichloromethyl) carbonate, C3Cl6O3) is a actinic admixture that is acclimated as a safer acting for phosgene, because at allowance temperature it is a solid crystal, as against to phosgene which is a gas. Triphosgene crystals decompose at about 130 °C, although, the atomization temperature of admixed samples can be abundant lower. Triphosgene is acclimated in amoebic amalgam to band one carbonyl accumulation to two alcohols, as in the amalgam of octalactin B. It is able by all-embracing chlorination of dimethyl carbonate.Triphosgene is acutely acid to the eyes and skin. Avoid acquaintance and inhalation. Use able claimed protection. Handle alone in a actinic anger hood. Keep deeply closed. Abundance in a cool, dry place.
