“…Song estimated that the global demand for CO 2 ‐derived chemicals and materials would utilize up to 720 megatons of CO 2 , and Drummond already recalculated that even if this value were doubled, the total CO 2 consumed globally through chemical utilization would be about 5% of the total anthropogenic emissions. Nevertheless, CO 2 is a potential source of carbon to synthesize other substances with higher thermodynamic value, such as urea, salicylic acid (Kolbe‐Schmitt reaction), methanol (using H 2 from syngas), polymeric carbonate esters, cyclic carbonate, dimethyl carbonate, isocyanates, esters and lactones, and polycarbonate . Low molecular weight organic compounds (e.g.…”
