In this study, new quaternary bis(ammonium) salts with alkyl-1,X-bis(dimethyldecylammonium) cation and saccharinate, acesulfamate, lactate and pyroglutamate anions were synthesized and characterized by H and C NMR spectroscopy. Thermal gravimetric and differential scanning calorimetry analyses confirmed that all salts were thermally stable and the majority of them exhibited melting points below 100 °C. The physicochemical properties (viscosity, density, refractive index values, and solubility) of the obtained salts were determined for three compounds with lactate anions. All the tested salts have suitable properties which, in practical application, will reduce the losses caused by the most important storage insects. Most of the synthesized ionic liquids had comparable or better deterrent activity than azadirachtin-an alkaloid known as the most active antifeedant.
在本研究中，合成了带有烷基-1,X-双（二甲基癸基铵）阳离子以及糖精、乙酰磺胺酸钾、乳酸盐和焦谷氨酸盐阴离子的新型季铵双（铵）盐，并通过氢核磁共振光谱和碳核磁共振光谱对其进行了表征。热重分析和差示扫描量热法分析证实，所有盐类均具有热稳定性，且它们中的大多数熔点低于100℃。针对三种含乳酸根阴离子的化合物，测定了所得盐的物理化学性质（粘度、密度、折射率值和溶解度）。所有测试盐均具有合适的性质，在实际应用中，这将减少由最重要的仓储害虫造成的损失。大多数合成离子液体具有与印楝素相当或更好的驱避活性，印楝素是一种被认为是最具活性的拒食剂的生物碱。
