Thermodynamics of cellulose dissolution in an imidazolium acetate ionic liquid†
Abstract
The heat of dissolution of cellulose in one imidazolium acetate ionic liquid was determined experimentally. The value of −132 ± 8 J g−1 indicates that the dissolution is exothermal thus confirming energetically favourable cellulose–ionic liquid interactions but indicating that an increase in temperature does not thermodynamically favour the dissolution process.
