Abstract

The kinetics of lignin methylsulfonation were studied in solution by using differential scanning calorimetry (DSC) techniques under an isothermal program, at 55, 65, 75 and 85°C, respectively. It was found that activation energy, E_α = 41.26 kJ/mol, and preexponential factor A was 1.85×10³ s^-1.
