Exposure of R-12 or R-22 to high heat can produce acids. Which acids are formed?

High heat causes halogenated refrigerants to break down and release chlorine and fluorine. R-12 and R-22 contain chlorine and fluorine, so when they are heated, they form hydrochloric acid and hydrofluoric acid. These acids are highly corrosive and can damage equipment and be hazardous to people. The other acids listed would require elements or reaction pathways not present in these refrigerants, so they don’t form from heating R-12 or R-22.
