Non-ozone-depleting hydrofluorocarbons

摘要

The state-of-the-art of transition of the chemical sector producing ozone-depleting substances (ODS) in Russia to non-ozone-depleting substances (NODS) is considered.The review summarizes the studies conducted by the Russian Scientific Center "Applied Chemistry" (St.Petersburg) and a number of Russian Academy Institutes including substantiation for the production methods of non-ozone-depleting hydrofluorocarbons;the most probable chemical mechanisms of their synthesis;the basis for standard process flow diagrams to be used in their full-scale manufacture;and the information on actual and newly created NODS production facilities in the Russian Federation.
