Applications of Reaction Calorimetry in Lignin Chemistry

Abstract
he thermodynamic properties of lignin and its solutions are important in the design and operation of the machines used in the biomass biorafination schemes. In the literature, there are few thermodynamic data on the main chemical components of biomass (cellulose, hemicellulose and lignin). In this paper we present the heat dissolution (ΔHdis) of the lignin alkaline solutions obtained by the reaction calorimetry. Lignin is characterized by insolubility in most simple solvents. The solubility of lignin preparations also depends on the method used to isolate them. Since most of the applications in which lignin is subjected to chemical reactions involves the dissolution of lignin, it is very important to know the thermodynamic properties of these solutions as well as the characterization of chemical reactions in terms of heat of reaction
