Disclosed are ionic liquids and methods of preparing ionic liquid compositions of active pharmaceutical, biological, nutritional, and energetic ingredients. Also disclosed are methods of using the compositions described herein to overcome polymorphism, overcome solubility and delivery problems, to control release rates, add functionality, enhance efficacy (synergy), and improve ease of use and manufacture.
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
