Ionic liquids (IL) have emerged as the next-generation “green” solvent that can replace traditional organic solvent due to properties such as high thermal stability and no vapor pressure. However, their increased usage inevitably allows them to find their way into the environment. The objective of this study was to evaluate the role of autotrophic ammonia-oxidising bacteria (AOB) in the potential removal of 1-dodecylpyridinium chloride ([DPy]+Cl) in both short- and long-term studies. In short-term batch experiments, it was observed that a notable amount of [DPy]+ can be removed by the AOB culture with the removal mechanism being biodegradation and absorption, with the latter playing a greater role. It was also found that [DPy]+ can be released back into the liquid phase when AOB’s preferred substrate, NH3, was present. In the long-term study, [DPy]+Cl was successfully biodegraded and a total of nine transformation products were identified. The biodegradation pathway was also proposed. This study demonstrated that [DPy]+Cl can be biol. transformed by enriched AOB culture and the accumulation of the byproduct did not show long-term neg. impact on AOB activities. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Application In Synthesis of 1-Dodecylpyridin-1-ium bromide).
1-Dodecylpyridin-1-ium bromide (cas: 104-73-4) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Reduced pyridines, namely tetrahydropyridines, dihydropyridines and piperidines, are found in numerous natural and synthetic compounds. The synthesis and reactivity of these compounds have often been driven by the fact many of these compounds have interesting and unique pharmacological properties.
