synthesized. The obtained compounds differed in terms of the substitution of the phenoxyethylammonium group in the ring (the presence of a methyl group in the meta or para positions and the presence of chlorine in the para position) as well as the length of the alkyl chain (from hexyl to tetradecyl). The basic physicochemical properties of the obtained ionic liquids (solubility and thermal stability) were characterized
摘要 合成了10种含有(4-
氯-2-甲基苯氧基)
乙酸(MCPA)阴离子和多米芬衍生的苯氧基乙基
铵阳离子的
离子液体。所得化合物的不同之处在于环中苯氧基乙基
铵基团的取代(间位或对位存在甲基,对位存在
氯)以及烷基链的长度(从己基至
十四烷基)。对所得
离子液体的基本理化性质(溶解度和热稳定性)进行了表征,并确认了它们的结构。在温室条件下使用矢车菊(Centaurea cyanus L.)作为试验植物测试了化合物的除草活性。
