and dodecylmethylene-1,12-bis(decyldimethylammonium), including two different herbicidal anions exhibiting different modes of action, were synthesized and characterized. One herbicide incorporated into the HILs was a tribenuron-methyl belonging to ALS inhibitors, while the second herbicidal anion was a synthetic auxin that acts as a growth regulator, namely 2,4-dichlorophenoxyacetate (2,4-D), 2-(2,
在本研究的框架内,合成了含有四亚甲基-1,4-双(癸基二甲基铵)和十二烷基亚甲基-1,12-双(癸基二甲基铵)的双阳离子除草离子液体(HIL),包括两种表现出不同作用模式的不同除草阴离子和特点。加入 HIL 的一种除草剂是属于 ALS 抑制剂的苯磺隆,而第二种除草阴离子是一种合成生长素,可作为生长调节剂,即 2,4-二氯苯氧基乙酸酯 (2,4-D)、2-(2 ,4-二氯苯氧基)丙酸酯, (2,4-DP), 2,4,5-三氯苯氧基乙酸酯 (2,4,5-T), 4-氯-2-甲基苯氧基乙酸酯 (MCPA), 2-(4-氯- 2-甲基苯氧基)丙酸酯(MCPP)和4-氯苯氧基乙酸酯(4-CPA)。发现所得产品不稳定且分解,这可归因于苯磺隆的磺酰脲桥中存在一个额外的甲基。合成的 HILs 对极性和半极性溶剂表现出良好的亲和力,乙酸乙酯和己烷是唯一不溶解 HILs 的溶剂。温室测试表明,大多数获得的 HIL
