Chemically assisted degradation of 1,3-dioxo-2-difluoromethylene-4-trifluoromethoxy-5-difluoroammonium acetate dioxole

Abstract

Recently, there has been a great strive to find new and efficient methods for the degradation of perfluorinated alkylated substances.In this research work, we present recent advancements and results in the degradation of the surfactant “cC6O4-NH4+” (I) (1,3-dioxo-2-difluoromethylene-4-trifluoromethoxy-5-difluoroammonium acetate dioxole) which demonstrates that it can be efficiently degraded in mild conditions, even at 20 °C.The results of several different and innovative chemical strategies, such as DMSO induced decomposition at mild temperatures, thermal decomposition, acid/base chemistry induced decomposition, all of which decomposed cC6O4 to CO2 + HF/F− in many cases ≥ 99.9%mol will be presented. All results will be supported by the respective kinetics, rates of reaction, thermodynamic reaction parameters, mechanisms of reaction, decomposition products, qualitative and quantitative spectroscopic analyses.
