Scientific Research Applications

Oxyfluorination of HydrocarbonsThe oxyfluorination of hydrocarbons, including ethene, has been a significant area of research for enhancing reactant conversion and selectivity towards valuable chemical intermediates. A study conducted by Albonetti et al. (2008) explored the oxyfluorination of ethene using metal fluorides. They discovered that mixed fluorides with a fluoroperovskite structure, such as AgCuF3, led to improved conversion and higher selectivity to vinyl fluoride over single metal fluorides. This process, however, faces challenges such as the regeneration of Ag° formed during oxyfluorination, prompting the search for new metal fluorides as catalysts. The formation of CO2 from secondary reactions due to the presence of metal oxides in the catalysts was noted, highlighting the complexity and potential of this reaction mechanism for industrial applications Albonetti et al., 2008.

Environmental Presence and Impact of Brominated CompoundsThe environmental occurrence and impact of brominated compounds, including novel brominated flame retardants (NBFRs), in indoor air, dust, and consumer goods have been extensively reviewed. Zuiderveen et al. (2020) provided a critical review summarizing the occurrence of 63 NBFRs across various matrices and highlighted the need for more research on their occurrence, environmental fate, and toxicity. This review underscores the emerging concern regarding the widespread application of NBFRs and the significant knowledge gaps that exist for many of these compounds, pointing to the need for comprehensive monitoring and optimized analytical methods Zuiderveen et al., 2020.

Selective Hydrogenation of Ethyne and EtheneThe selective hydrogenation of ethyne and ethene on palladium catalysts has been reviewed by Bos and Westerterp (1993), focusing on the progress made in understanding the kinetics and mechanism of this reaction. The review points out that the classical view of selectivity being solely due to thermodynamic factors is an oversimplification. It highlights the role of different active sites and the presence of complex reactions beyond the main hydrogenation process. This insight into the selective hydrogenation of ethyne and ethene opens avenues for refining industrial processes involving these compounds Bos & Westerterp, 1993.

Bioremediation of Chlorinated EthenesThe natural attenuation of chlorinated ethenes, such as vinyl chloride, in hyporheic zones (the interface between river water and groundwater) has been reviewed. Weatherill et al. (2018) discuss the biogeochemical processes that facilitate the degradation of these contaminants, highlighting the potential of these zones to act as natural bioreactors. This review provides valuable insights into the mechanisms through which anaerobic and aerobic biotransformation processes can synergistically reduce contaminant fluxes to surface water, emphasizing the importance of understanding these processes for the development of effective bioremediation strategies Weatherill et al., 2018.
