Irregular solution thermodynamics of wood pulp in the superbase ionic liquid [m-TBDH][AcO].

ABSTRACT: Knowledge of solution thermodynamics is fundamental for solution control and solvent selection processes. Herein, experimentally determined thermodynamic quantities for solutions of wood pulp (hardwood dissolving pulp, i.e. cellulose) in [m-TBDH][AcO] are presented. Model-free activities (a _i,j) and associated mass fraction (w _i,j) activity coefficients (Ω _i,j), are determined to quantify inherent solution non-ideality. Access to the Gibbs energy of mixing, G _mix, in combination with associated partial molar thermodynamic quantities, reveal strong enthalpically favourable (exothermic) interactions due to solvent-j and solute-i contact-encounters.
