1- Butyl-3-methylimidazolium C4mim

Alammar and Mudring [17] have also synthesized ZnO in the form of nanorods with lengths from 50-100 nm and diameters of about 20 nm (Fig. 8.5.) using the ionic liquid l-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide, [C4mim][Tf2N]. 

A broader exploitation of cellulose solubility in ionic liquids lies in modification of cellulose into more useful forms. Cellulose acetate is currently the most useful derivative of cellulose, with uses in photographic film, as a synthetic fibre and as a component of adhesives. Acetylation of cellulose has been carried out effectively in l-allyl-3-methylimidazolium chloride [Amim][Cl], [C4mim CI], [C2mim][Cl], l-butyl-2,3-dimethylimidazolium chloride [C4dmim][Cl] and l-allyl-2,3-dimethyl-imidazolium bromide [Admim][Br] [136, 159-162], The first report of cellulose acetylation in an ionic liquid involved a one-step reaction in [Amim][Cl] without catalyst, yielding cellulose acetate with a controllable degree of substitution [136], Yields of cellulose acetate of up to 86% have been obtained via reaction in [C4mim] [Cl] at 80 °C for 2 h [160],...

Hard Lewis acid chloroaluminate ionic liquids show intense catalytic activity in the Friedel-Crafts acylation reaction however, they suffer from the same issues as anhydrous aluminum chloride. i Of particular interest to these reactions, aluminum chloride may be replaced by indium trichloride to form chloroindate(III) ionic liquids. The advantage of using indium trichloride compared with aluminum chloride is represented by its hydrolytic stability and reduced oxophilicity. Chloroindate(III) ionic liquids are synthesized by mixing l-butyl-3-methylimidazolium chloride [C4mim]Cl with anhydrous indium trichloride at 80°C. In the benzoyla-tion of anisole with benzoic anhydride (BAN) at 80°C, the best yield of... 

The ionic liquids used in this work are l-butyl-3-methylimidazolium bis (trifluoromethyl)sulfonyl amide [C4mim] [NTfa],... 

Tin monosulfide (SnS) is a promising material for thin-film photovoltaic applications. The semiconductor has an indirect band gap of 1.1 eV and a direct band gap of 1.3 eV. Furthermore, it shows intrinsic p-type conductivity. Recently, Steichen et al. [38] reported a direct electrodeposition of p-type SnS on molybdenum in l-butyl-3-methylimidazolium dicyanamide ([C4mim][N(CN)2]) iraiic liquid containing elemental sulfur and SnCl2 above 100 °C. The authors proposed that...

Figure 7.2a and b depicts the numbering scheme and the model for the molecular orientation of the 1-butyl-3-methylimidazolium cation, [C4mim] in ionic liquids at the air-liquid interface, respectively. SFG results show that the butyl chain of the cation extends towards the gas phase witii the imidazolium ring lying parallel to the surface plane. This configuration has been found to be consistent, regardless of the anion [32], for 1-butyl-3-methylimidazolium room-temperature ionic liquids, particularly where the anions are composed of Br , r, [PFg] ,... 

As a result, there are few straightforward pairwise comparisons that can be made between salts of a cation of interest with a common counter-anion. Nevertheless, the availability of structural data for 37 l-ethyl-3-methylimidazolium [Table 11.231 and 27 l-butyl-3-methylimidazolium [Table 11.231 salts provides an opportunity for a series of comparisons involving salts [C2mim][A] and [C4mim][A], where [A] = [CFgSOg]", [Au ClJ or [A1 0CH(CF3)2 4] , and the 2 1 compounds [Rmim]2[Fe Cl4] or [Rmim]2[Co Cl4] (dealt with in Section 11.8 or 11.5.6.31. 

Some representative calculations, which were performed using the pure fluid and binary parameters of Tsioptsias et al. [69], are illustrated in Figures 2.12 and 2.13, for the LLE of water-1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C4mim+][Tf2N ]) system, and the VLE of acetone-1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [C4mim+][Tf2N ] mixture.
