在这项工作中,合成并表征了十六种具有苯氧基羧酸根阴离子的新型吡咯烷鎓除草离子液体(HIL)。确定了烷基或烷氧基甲基链长和阴离子类型对物理化学性质(如HIL的密度,粘度和折射率)以及对热稳定性和表面活性的影响。制备的HIL的结构中存在的氧会显着影响其热和表面性能。此外,通过在温室实验中使用普通的羊腿(Chenopodium album L.)作为测试植物来测试除草功效。新型吡咯烷鎓离子液体比市售除草剂更有效。
A new one-step procedure is described for the synthesis of disubstituted imidazolium chlorides. 1,3-Dialkoxymethylimidazolium chlorides thus obtained can be employed as synthetic precursors of symmetrical ILs. The salts have been found to exhibit antimicrobial activity and an antielectrostatic effect. Their densities and viscosities have been determined and are reported herein. It has also been demonstrated

New choline-like quaternaryammoniumchlorides were obtained. The work-up procedure of synthesis was quick and efficient. The obtained chlorides showed anti-microbial activities. Quaternaryammoniumchlorides derivatives of deanol esters exhibited strong activity and wide anti-bacterial spectra, similar to the activity of benzalkonium chloride. The relationship between chemical structure and anti-microbial

A novel class of functionalized cationic surfactant has been obtained. The work-up procedure of synthesis is very simple, the yield is high and the pyridiniumsalts with alkoxymethyl hydrophobic group are easily purified. All the salts examined showed anti-microbial activities. Some of them exhibited strong activity and wide anti-bacterial spectra similar to the activity of benzalkonium chloride. The
Iminiumverbindungen gegen Bakterien und Pilze, 29. Mitt.: 3-Alkoxymethyl-1-ethyl-, 3-Alkylthiomethyl-1-ethyl-, 3-Alkoxymethyl-1-butyl- und 3-Alkylthiomethyl-1-butylbenzimidazolium-chloride
Synthese und antimikrobielle Wirkung der 3‐Alkoxymethyl‐1‐ethyl‐, 3‐Alkylthiomethyl‐1‐ethyl‐, 3‐Alkoxymethyl‐1‐butyl‐ und 3‐Alkylthiomethyl‐1‐butylbenzimidazoliumverbindungen werden beschrieben. Die Verbindungen wurden durch Quaternisierung von 1‐Ethyl‐ bzw. 1‐Butyl‐benzimidazol mit Chlormethylalkylethern bzw. Chlormethylalkylsulfid gewonnen. Die bakteriostatische Wirkung wurde gegenüber 13 Bakterien‐ und
