Solvent effects on the ability of KF/Al2O3 supports to degrade the warfare agent sulfur mustard (HD) were explored. RP-KF/Al2O3 possessing hydroxide ions and ECUF/KF/Al2O3 holding fluoride ions were examined. Reactions on RP-KF/Al2O3 containing 10 wt % of organic solvents were faster than those on ECUF/KF/Al2O3. Additionally, RP-KF/Al2O3 led to elimination products, while ECUF/KF/Al2O3 mainly led to
研究了溶剂对KF / Al 2 O 3载体降解作战剂硫芥末(HD)的能力的影响。研究了具有氢氧根离子的RP-KF / Al 2 O 3和具有氟离子的ECUF / KF / Al 2 O 3。在含有10wt%有机溶剂的RP-KF / Al 2 O 3上的反应比在ECUF / KF / Al 2 O 3上的反应更快。此外,RP-KF / Al 2 O 3导致了淘汰产品,而ECUF / KF / Al 2 O 3主要导致替代衍生物。将溶剂量增加至90wt%导致反应速率降低。讨论了溶剂同一性/量和活性物质的重要性。
