1. Oxidation of glycerol with dii. FINO3 gives glyceric acid and tartronic acid.
2. Oxidation of glycerol with Conc. HNO3 gives mainly glyceric acid.
3. Oxidation of glycerol with bismuth nitrate gives as meso oxalic acid.
4. Oxidation of glycerol with Br2 /H2O (or) NaOBr (or) Fenton reagent (FeSO4 + H2O2)
5. gives a mixture of glyceraldehyde and dihydroxy acetone(glycerose).
6. On oxidation with HIO4 or Lead tetra acetate (LTA) it gives formaldehyde and formic acid.
7. Acidified KMnO4 oxidises glycerol into oxalicacid.
