A Mo(OCH₂CH₃)_x/NaCl catalyst showed high efficiency in supercritical ethanol without adding H₂ in the conversion of Kraft lignin to chemicals, including C₆ alcohols, C₈-C₁₀ esters, benzyl alcohols and arenes. Control experiments were done with MoCl₅, NaOC₂H₅ and the physical mixture of them. The Mo(OCH₂CH₃)_x/NaCl catalyst exhibited superior activity among the samples examined. The overall yield increased as the reaction temperature increased from 260 to 300 °C. The yield of aromatic compounds achieved 303mg/g lignin over the Mo(OCH₂CH₃)_x/NaCl catalyst at 300oC for 6h. MoCl₅ and NaOC₂H₅ forms Mo(OCH₂CH₃)_x in the catalyst preparation, which behaves as the active species in Kraft lignin conversion. The primary aromatics formed from the catalytic lignin depolymerization steps may undergo secondary reactions to form the final products.
