The synthesis of a series of ionic liquids using 1-butyl 3-methylimidazolium (Bmim⁺) as a cation and different amino acids (AA) as anions (Bmim[AA]) is described. These ILs were used for the first time as reaction media to achieve more eco-friendly Paraoxon degradation. The results show that the degradation of Paraoxon in these Bmim[AA]s is accomplished with great efficiency and without an extra nucleophilic agent. Therefore, we propose that all the Bmim[AA]s used in this study have a dual role in the outcome of this reaction; as a nucleophile and a solvent to carry out degradation of the organophosphorous pesticide, Paraoxon. Both kinetics and product distribution results found in this study for Paraoxon degradation turned out to be promising, because this process is achieved in a reaction medium with a better environmental profile.

氨基酸离子液体（Bmim [AA]）对有机磷农药Paraoxon®降解的双重作用

使用1-丁基3-甲基咪唑鎓（Bmim ⁺描述了作为阳离子的阳离子和不同的氨基酸（AA）作为阴离子（Bmim [AA]）。这些IL首次用作反应介质，以实现更环保的Paraoxon降解。结果表明，在这些Bmim [AA]中降解对氧磷的效率很高，并且不需要额外的亲核试剂。因此，我们建议本研究中使用的所有Bmim [AA]在该反应的结果中均具有双重作用。作为亲核试剂和溶剂来降解有机磷农药对氧磷。在这项研究中发现的对氧磷降解的动力学和产物分布结果都很有希望，因为该过程是在具有更好环境分布的反应介质中完成的。
