A thermochemical
study of the protic ionic liquid 1,5-diazabicyclo[4.3.0]non-5-enium
acetate ([DBNH][OAc]), a prospective cellulose solvent considered
for the Ioncell-F process, was carried out. The heat capacities of
1,5-diazabicyclo[4.3.0]non-5-ene (DBN) and [DBNH][OAc] were measured
by differential scanning calorimetry (DSC) at 223–323 and 273–373
K temperature ranges, respectively. The enthalpies of fusion and synthesis
reaction of [DBNH][OAc] were measured by DSC and reaction calorimetry,
respectively. The gas-, liquid-, and solid-phase enthalpies of formation
of [DBNH][OAc] and DBN were determined using calorimetric and computational
methods. The enthalpy of vaporization of [DBNH][OAc] was estimated
from the formation enthalpies. The activity coefficients at infinite
dilution of 17 and the enthalpies of solution at infinite dilution
of 25 organic solutes in [DBNH][OAc] were measured by gas chromatography
and solution calorimetry methods, respectively. The obtained data
will be used in the design and optimization of the Ioncell-F process.
