Heating up: Improved recyclability is necessary for ionicliquids destined for wood‐based bioprocessing platforms. New “distillable” molten acid–baseconjugates efficiently dissolve cellulose at temperatures of 100 °C. Increased temperature induces a shift of the acid–base equilibrium toward the neutral species (see picture, TMG=1,1,3,3‐tetramethylguanidine), thus affording a vapor pressure and allowing
