“…In 1970, SNPE exploited the phosgenation of glycols that had long been a prominent technology but which, unfortunately, led to the production of chlorinated waste that caused a major adverse environmental impact. Whilst the major positive aspect of using phosgene is its high reactivity, the drawbacks include limitations to transport and storage, safety measures in handling, and the disposal of large amounts of end -products [1] . Environmental regulations and risk minimization, however, do not ensure that such technology can fi t in with the market expansion of the two major acyclic carbonates, namely dimethyl carbonate ( DMC ) and diphenyl carbonate ( DPC ), and that of ethene carbonate ( EC ) and propene carbonate s ( PC ).…”
