Some features of the environmentally friendly “phosgene-free” polycarbonate production technology

The paper considers the main factors of environmental safety of the "phosgene-free" polycarbonate production technology in comparison with the processes based on the use of phosgene. Historical stages of development of this technology and the main technological solutions ensuring its effectiveness are reviewed. The advantages of the “phosgene-free” technology are demonstrated using the example of Kazanorgsintez PJSC, which created the only polycarbonate industrial unit in the Russian Federation. The main characteristics of the polycarbonates produced are presented.
