experiment and further confirmed by orthogonal experimental method. Among these reaction conditions, the optimal combination was the reaction temperature of 40°C, ILs/O molar ratio of 0.2:1, px/O molar ratio of 12:1, and the reaction time of 30 min. Furthermore, [Pip1,8]Br‐2AlCl3 had excellent stability and can be recycled 14 times. It was the high‐efficiency catalytic activity and prominent recyclability

Synthesis and Surface Properties of Piperidinium-Based Herbicidal Ionic Liquids as a Potential Tool for Weed Control
A series of piperidinium-based herbicidal ionic liquids (HILs) were synthesized and investigated. The designed HILs, obtained with high yields, consisted of cation 1-alkyl-1-methylpiperidinium with surface activity and a commercially available herbicidal anion: (3,6-dichloro-2-methoxy)benzoates (dicamba). The above-mentioned compounds were characterized in terms of surface activity and phytotoxicity
合成并研究了一系列基于哌啶鎓的除草离子液体 (HIL)。以高产率获得的设计 HIL 由具有表面活性的阳离子 1-烷基-1-甲基哌啶和市售除草阴离子:(3,6-二氯-2-甲氧基)苯甲酸盐(麦草畏)组成。上述化合物的特征在于表面活性和植物毒性。与商业 Dicash 的润湿性相比,在所有 HIL 的润湿性更高的情况下获得了初步结果,碳链中具有 18 个原子的 HIL 在润湿表面(杂草和作物叶子)方面效果最佳,因此一滴具有短烷基的 HIL链条(C 8 –C 10) 不能滑下一片叶子。我们的研究结果表明,HIL 液滴的润湿性或流动性因植物种类而异。此外,在这项研究中,通过 zeta 电位和原子力显微镜测量,我们提供了确凿的证据证明烷基链伸长在 HIL 表面特性的演变中起着重要作用。
Effect of 1-alkyl-1-methylpiperidinium bromides on lipids of fungal plasma membrane and lung surfactant
ergosterol (ERG)–the main components of lung surfactant and fungal plasma membrane, respectively and their mixtures with phospholipids and sterols. The mixtures were chosen as the representatives of target and non−target organisms. The surface pressure−area isotherms were obtained by compressing monolayers in the presence of [MePipCn][Br] in the subphase. The results were analyzed in terms of area expansion/contraction
