Synthesis of renewable acetic acid from CO2 and lignin over an ionic liquid-based catalytic system

Abstract

Synthesis of renewable acetic acid from CO₂ and lignin was effectively achieved over an ionic liquid (e.g., [BMIm][Cl])-based catalytic system containing Ru–Rh bimetal catalyst (Ru₃(CO)₁₂ and RhI₃) and LiI. As far as we know, this is the first initiative to produce acetic acid from lignin and CO₂.
