Tris-imidazolium and benzimidazolium ionic liquids: a new class of biodegradable surfactants was written by Al-Mohammed, Nassir N.;Duali Hussen, Rusnah Syahila;Alias, Yatimah;Abdullah, Zanariah. And the article was included in RSC Advances in 2015.Name: 1-Octyl-1H-imidazole This article mentions the following:
Based on imidazolium and benzimidazolium, two series of novel tris-cationic ionic liquid surfactants containing ester groups were synthesized simply from readily available starting materials in high yields. Biodegradability and surfactants properties of the tris-imidazolium and tris-benzimidazolium ionic liquids were investigated. Some compounds showed assembly behavior in the pure form (i.e. absence of solvent) and in the presence of polar or nonpolar solvents. These surfactants are effectively reducing the surface tension of water in the range of 28-31 mN m-1. Through using the ‘Closed-Bottle Test’ OECD 301D, the incorporation of alkyl or Ph side chains with ester groups in the same mol. significantly improved the biodegradation compared to sodium n-dodecyl sulfate (SDS) as a reference The aliphatic alkyl side chain, i.e., Bu, hexyl, octyl, decyl and dodecyl, in both imidazolium and benzimidazolium ionic liquids had marked increasing biodegradation and phase behavior results compared to aromatic side-chains. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Name: 1-Octyl-1H-imidazole).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole has become an important synthon in the development of new drugs. This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.Name: 1-Octyl-1H-imidazole
