提高环境质量是可持续农业的关键原则之一，这意味着减少合成农药和化肥的使用。绿色化学提供了一系列创新的方法，以开发安全和高效的化学转化方法，在温和的条件下转化为无毒和容易生物降解的产品。开发化学去污有机磷神经毒剂和杀虫剂的新战略是一个迫切需要关注的问题。已证明了肟类化合物作为官能化的有组织的分子系统具有应用价值。在这项研究中，探讨了肟基吡啶表面活性剂3-羟亚氨甲基-1-烷基-溴化吡啶(烷基=CnH_2n+1，n=10，12，14，16)和4-羟亚胺甲基-1-烷基吡啶(烷基=CnH_2n+1，n=10，12)对农药对氧磷(NPDEP)和甲基对氧磷(NPDMP)在混合溶剂中的亲核效率。
The enhancement of environmental quality is one of the key principles of sustainable agriculture, which points to less use of synthetic pesticides and chemical fertilizers. Green chemistry offers an array of innovative approaches to develop safe and efficient methods of chemical transformation toward nontoxic and readily biodegradable products under mild conditions. The development of new strategies for chemical decontamination of organophosphorus nerve agents and pesticides is an issue of immediate concern. Oximes have been demonstrated to find an application as functionalized organized molecular systems. In this study, kinetic investigations have been explored to estimate the nucleophilic efficiency of the oxime-functionalized pyridinium surfactants 3-hydroxyiminomethyl-1-alkylpyridinium bromide (alkyl = CnH2n+1, n = 10, 12, 14, 16) and 4-hydroxyiminomethyl-1-alkylpyridinium bromide (alkyl = CnH2n+1, n = 10, 12) for the hydrolysis of the pesticides paraoxon (NPDEP) and methyl paraoxon (NPDMP) in mixed m...
