Value-added Chemicals from Crude Glycerol

According to a new research paper, bBoth conventional catalysis and biological conversion can offer promising opportunities for the biodiesel industry to convert crude glycerol into a wide variety of value-added products.

A list of compounds that can be made via oxidation or reduction of glycerol are:

  1. Tartronic acid (C3H3O5)
  2. Dihydroxyacetone
  3. Mesoxalic acid (Ketomalonic acid)
  4. Glyceraldehydes
  5. Glyceric acid
  6. Malonic acid
  7. Hydroxypyruvic acid
  8. Lactic acid
  9. Pyruvic acid
  10. Propylene glycol
  11. Propionic acid
  12. Glycidol
  13. Acrylic acid
  14. Propanol
  15. Isopropanol
  16. Acetone
  17. Propylene oxide
  18. Propionaldehyde
  19. Allyl alcohol
  20. Acrolein
  21. Hydrogen


Production of various coproducts via anaerobic fermentation of glycerol by clostridia:

  1. 1,3-PDO
  2. Acetic acid
  3. Butyric acid
  4. Lactic acid
  5. Succinic acid
  6. Butanol
  7. Ethanol
  8. Acetone
