Abstract
The present disclosure relates to a method of converting glycerol into organic reaction products. The method may include mixing glycerol with a monohydric alcohol. The mixture of glycerol and monohydric alcohol is then reacted in the presence of a heterogeneous nano-structured catalyst, wherein the monohydric alcohol is present at subcritical/supercritical temperatures and pressures. This converts the glycerol into one or more reaction products, wherein the reaction products include an oxygenated organic reaction product. Ninety percent or greater of the glycerol is converted.
