One-pot synthesis of symmetric imidazolium ionic liquids N,N-disubstituted with long alkyl chains

Abstract

The modified Debus–Radziszewski reaction was used as a one-pot on-water reaction to allow a greener synthesis of long-chain 1,3-dialkylimidazolium acetate ionic liquids in high yield from long-chain linear amines.

Ionic Liquid Melting Points: Structure–Property Analysis and New Hybrid Group Contribution Model

“…Furthermore, they are widely available from commercial sources, and they tend to have favorable properties for many applications. The development of efficient synthetic routes to certain types of ILs simplifies the synthesis of homogolous series, which in turn has led to the availability of significant quantities of data for such series. , The group titled “other” represents those ILs that do not contain any of the more common cation core structures and, therefore, do not have a significant number of data points. In total, 585 different cations are included in the database.…”

Stability Enhancement of Zinc‐Ion Batteries Using Non‐Aqueous Electrolytes

“…Such groups possess several beneficial basic features such as intrinsic ion conductivity, negligible volatility, high chemical/thermal stability and a wide electrochemical stability window. According to the literature, there are mainly two groups of conventional RTILs being studied in Zn electrodeposition and in Zn battery research, classified by their cation species e. g., alkyl imidazolium and alkyl pyrrolidinium [26] . Simons et al.…”

“…Alkyl Imidazolium salts, which have a melting point lower than room‐temperature are classified as RTILs. Due to their heterocyclic structure, imidazolium ILs are found to be thermally and electrochemically stable [26] . According to the literature, several alkyl imidazolium ILs can dissolve Zn salt, having the same anion species i. e., Zn(OTf) 2 in [C 2 mim]OTf and can provide Zn deposition.…”

“…According to the literature, there are mainly two groups of conventional RTILs being studied in Zn electrodeposition and in Zn battery research, classified by their cation species e. g., alkyl imidazolium and alkyl pyrrolidinium. [26] Simons et al (2014) [27] indicated the possibility of using RTILs in Zn battery applications. 1-ethyl-3methylimidazolium dicyanamide ([C 2 mim]dca) and 1-butyl-1methylpyrrolidinium dicyanamide ([C 4 mpyrr]dca), containing 3 wt % water and 9 mol % Zn dicyanamide [Zn(dca) 2 ], have been examined as an electrolyte for a Zn symmetrical (Zn/Zn) cell.…”

Imidazolium-Containing Hybrid Organic–Inorganic Materials for the Conversion of CO2: Unveiling the Key Role of the Ionic Template

“…34 The replacement of acetate by chloride or bromide that are more active for the catalytic conversion of CO 2 to cyclic carbonate is thereafter achieved by a total neutralization of the acetate using strong acids such as HCl or HBr. 35 Here, we present for the first time the one-pot synthesis of an imidazolium-containing organosilicon (Si-imi-Si) using the Debus−Radziszewski reaction, as depicted in Scheme 1. The AMS material was thereafter prepared using one of the most used anionic surfactants, sodium dodecyl sulfate (SDS; CH 3 (CH 2 ) 11 OSO 3 − Na + ).…”
