A wide range of ionic liquids, both water miscible and water immiscible, containing a diverse set of cations and anions, were screened for toxicity towards Escherichia coli K-12, using both Agar Diffusion tests and growth inhibition tests in liquid cultures. The data provide preliminary rules to enable the design of non-toxic ionic liquids for use in biocatalytic processes.
In this work we describe the synthesis and thermal properties of nine new salts derived from ammonium that incorporate alkanesulfonate and alkanesulfate anions. Their structures were confirmed by 1H and 13C NMR and HRMS-ESI. Their thermal properties were determined by differential scanning calorimetry (DSC). Three of the synthesized salts have been shown to be room temperature ionic liquids: N-eth
在这项工作中,我们描述了九种衍生自铵盐的新盐的合成和热学性质,这些盐结合了链烷磺酸根和链烷磺酸根阴离子。它们的结构通过1 H和13 C NMR和HRMS-ESI确认。它们的热性质通过差示扫描量热法(DSC)确定。已显示三种合成的盐为室温离子液体:N-乙基-N-(2-羟乙基)-N,N-二甲基丁烷磺酸铵,N-乙基N,N-二甲基丁基铵乙基硫酸盐和N-乙基N-(2-羟乙基)-N,N-二甲基乙基硫酸铵。在T = 298.15 K时测量了这三种离子液体的实验密度,声速,动态粘度和折射率。
