Superbase-based protic ionic liquids for cellulose filament spinning

Ultrastable superbase-derived protic ionic liquids.

Protic ionic liquids are synthesized via proton transfer from acids to organic bases. One of the key issues associated with conventional protic ionic liquids is the thermal instability resulting from temperature-induced decomposition via reverse proton transfer. This shortcoming significantly hampers the use of these protic ionic liquids in separations, electrochemical capacitors, fuel cells, a...

Cellulose hydrolysis with thermo- and alkali-tolerant cellulases in cellulose- dissolving superbase ionic liquids

Lithium coordination in protic ionic liquids.

The lithium ion-ion interactions in protic ionic liquids can be very different compared to those in aprotic ionic liquids. In this study we show that, for equal lithium ion concentration, the lithium coordination number in protic ionic liquids is lower than that in aprotic ones. This lower coordination makes lithium ions more "free" to move in protic ionic liquids and it might have an important...

Thermophysical properties of two ammonium-based protic ionic liquids.

Experimental data for density, viscosity, refractive index and surface tension are reported, for the first time, in the temperature range between 288.15 K and 353.15 K and at atmospheric pressure for two protic ionic liquids, namely 2-(dimethylamino)-N,N-dimethylethan-1-ammonium acetate, [N11{2(N11)}H][CH3CO2], and N-ethyl-N,N-dimethylammonium phenylacetate, [N112H][C7H7CO2]. The effect of the ...
