Atmospheric Lifetime of Novec 1230 fluid is 5 days. We also conducted relative rate experiments in a much more controlled environment where we put Novec 1230 fluid in a chamber and exposed it to ultraviolet light. In this case, Novec 1230 fluid is the unknown. We chose acetaldehyde as the reference compound because it has a well-documented UV absorbance spectrum, and it was known that, based on this spectrum, its lifetime by photolysis in the atmosphere was about five days. So we did a series of experiments: each compound independently in the chamber; both in the chamber at the same time. We exposed it to the same light sources and as a result we found that they decomposed at about the same rate. Which means that Novec 1230 fluid has an atmospheric lifetime of about five days. This was confirmation of what was predicted theoretically and clearly addresses the issue of environmental persistence in the atmosphere.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
