摘要
在这项研究工作中，我们介绍了降解表面活性剂 "cC6O4-NH4+" (I)（1,3-二氧代-2-二氟亚基-4-三氟甲氧基-5-二氟乙酸铵二氧戊环）的最新进展和成果，表明它可以在温和条件下，甚至在 20 °C 下高效降解。将介绍几种不同的创新化学策略的结果，如在温和温度下用二甲基亚砜诱导分解、热分解、酸/碱化学诱导分解，所有这些方法都能将 cC6O4 分解为 CO2 + HF/F-，在许多情况下分解率≥ 99.9%mol。所有结果都将得到相应的动力学、反应速率、热力学反应参数、反应机理、分解产物、定性和定量光谱分析的支持。
Chemically assisted degradation of 1,3-dioxo-2-difluoromethylene-4-trifluoromethoxy-5-difluoroammonium acetate dioxole
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.
期刊介绍：
The Journal of Fluorine Chemistry contains reviews, original papers and short communications. The journal covers all aspects of pure and applied research on the chemistry as well as on the applications of fluorine, and of compounds or materials where fluorine exercises significant effects. This can include all chemistry research areas (inorganic, organic, organometallic, macromolecular and physical chemistry) but also includes papers on biological/biochemical related aspects of Fluorine chemistry as well as medicinal, agrochemical and pharmacological research. The Journal of Fluorine Chemistry also publishes environmental and industrial papers dealing with aspects of Fluorine chemistry on energy and material sciences. Preparative and physico-chemical investigations as well as theoretical, structural and mechanistic aspects are covered. The Journal, however, does not accept work of purely routine nature.
For reviews and special issues on particular topics of fluorine chemistry or from selected symposia, please contact the Regional Editors for further details.
