“…Balasubramanian et al synthesized ADES using renewable p -toluene sulfonic acid ( p -SA) as HBD for lignin extraction from rice husks, achieving 83% yield. 52 Controlling the water content of ChCl : p -SA ADES within 26%, they found that adding water had a positive effect on lignin yield, reaching 94% at 5.3% water content but dropping to 47.9% when water was further increased to 26%. This phenomenon was probably attributed to water's influence on the physicochemical properties of DES.…”

“…96,97 Increasing the temperature and treatment duration have a similar effect on reducing the M w of D-lignin. 52,98 Another crucial factor affecting the M w of D-lignin is the solid loading, which tends to increase with higher solid loading due to the limited mass transfer effect of ADES during the treatment. This limited mass transfer effect, along with the minimal cleavage of ether bonds, results in a weak depolymerization effect on lignin.…”
