Two-step separation for enriching phenols and esters from base-catalyzed depolymerization of sorghum stalk

Two-step separation for enriching phenols and esters from base-catalyzed depolymerization of sorghum stalk

•Base-catalyzed depolymerization of sorghum stalk was conducted.•The suitable condition for total ESs yield was 280 °C with CaO/sorghum stalk ratio of 7:10 g/g.•Catalytic reactivity of bases for biomass increase in the order: Na2CO3
