Abstract: To examine the solvent isotope effect on hydrogen-transfer reduction of CO₂ into formate with glycerine by alkaline hydrothermal reaction, intermediates were identified by ¹³C-NMR, ¹H-NMR, ²H-NMR, LC-MS analyses. The results showed that (1) CO₂ was indeed converted into abiogenic formate; (2) a ketone carbonyl group as intermediate product was formed on hydrogen-transfer reduction of CO₂ into formate with glycerine by alkaline hydrothermal reaction; (3) acetol was the most probable intermediate in the first reaction by undergoing a dehydration rather than a dehydrogenation.
