Phosgene reaction with water
Did you know?
WebTriphosgene ( bis (trichloromethyl) carbonate ( BTC) is a chemical compound with the formula OC (OCCl 3) 2. It is used as a solid substitute for phosgene, which is a gas. [5] Triphosgene is stable up to 200 °C. [6] Triphosgene is used in a variety of halogenation reactions. [7] Preparation [ edit] This compound is commercially available. WebThe scrubber system should also be considered a potential source of water (vapor). • During and after reaction with BTC (homogeneous phase or biphasic systems), phosgene can usually be detected in the off-gases and all of the layers (i.e., organic and aqueous); this possibility should also be considered in cases of reactor cleaning, and so forth.
WebJul 27, 2024 · It reacts with water, forming carbon dioxide and hydrochloric acid. However, one must remember that this reaction is slow, which makes water a very ineffective phosgene scrubber! It is also quite reactive with various organic substances, which makes phosgene an important industrial chemical and precursor to things like plastics.
