Storage phosgene

By minimizing inventories of hazardous material, for example through just in time production the consequences of any accident will inevitably be reduced. As discussed above, storage of MIC was responsible for Bhopal and its use could have been avoided by using an alternative synthetic path phosgene, however, is required in both routes. Sometimes it is impossible (with current knowledge) to eliminate the use of a highly... 

Diphenyl carbonate is an important intermediate in the production of bisphenol-A-polycarbonate (BPA-PC). The technology shift from phosgene to DPC to produce BPA-PC on a commercial scale also allows the number of applications of this type of polymer to be increased for example, high-performance BPA-PCs utilized for information storage (e.g., DVDs) are prepared from high-purity DPC. The chemical route to this DPC brand is based on a two-step reaction, namely transesterification followed by disproportionation (Equations 7.4 and 7.5). 

Preparative Methods from (.)- )-1-(1-Naphthyl)ethylamine by reaction with Phosgene or by a method using Trichlorosilane. Handling, Storage, and Precautions stable when stored between 0 and 4 °C reacts with water highly toxic should be handled... 

The boiling point is an important characteristic of a war gas, not only because of its connection with vapour tension and therefore with the tactical aims attainable in warfare, but also because of its influence on the ease of storage and transport of the substance. A war gas whose boiling point is lower than ordinary temperatures, as, for example, phosgene, is difficult to pack and necessitates the use of refrigerating apparatus during transport in order to keep it below its boiling point. 

Phosgene is stored in cylinders like liquid chlorine. Iron containers which have been used for long periods for the storage... 

Note that the adduct (III) which can be stored at least one year at room temperature and which reverts easily to its components in solution was proposed as a convenient (safe ) storage system for phosgene under the term phosgene - in - a - can (Ref. 170).
