A Review on Catalytic Dehydration of Glycerol to Acetol

Abstract: The renewability of glycerol has made it an appealing medium for the processing of various compounds. Selective dehydration of glycerol to acetol is one of the promising glycerol valorizations. The performance and recent progress of those typical and most frequently mentioned catalysts for the synthesis of acetol from glycerol, including noble metals and transition-based metals, are summarized in detail. A Cu-based catalyst is identified as an appropriate catalyst for the synthesis of the glycerol dehydration … Show more

“…Regarding the taste, acetol can vary depending on the medium in which it will be dissolved (roasted or sweet), and it can also form an emulsion similar to yogurt. In addition to the food industry, it has interesting uses in the pharmaceutical, cosmetics and textile industries [59] …”

“…Dehydration needs to performed at a temperature of 280 to 350 C. 58 Acetol can be produced from glycerol with both heterogeneous and homogeneous catalysts. 59 Basu and Sen. 60 summarized the recent progress on common and typical catalysts used in the catalytic synthesis of acetone alcohols from glycerol, including noble metals and transition-based metals. On the other hand, the gas-phase dehydration of glycerol to acrolein is also a hot research topic in recent years.…”

“…Biomass valorization has attracted considerable attention as a future sustainable solution to produce value-added chemicals and fuels. Biodiesel is one example of such a product. Biodiesel is produced by transesterification of vegetable oils with alcohol, yielding ester and glycerol in a 10:1 ratio by volume. The glycerol obtained as a byproduct has a lower demand than diesel . Therefore, considerable attention has been given to upgrade glycerol to different platform chemicals. Ketalization or acetalization using glycerol is considered a promising valorization route to cyclic acetals . Glycerol levulinate ketal (GLK) has diverse functional groups comprising ester, acetal, and hydroxyl, which creates balanced hydrophilicity.…”
