Question

What is ‘Glycerose’? How is it prepared from glycerol?

Answer 1

Hint: The Glycerose is the mixture of two compounds forming from the oxidation of glycerol.

Complete step by step:
Let us know about the glycerol and glycerose first.
Glycerol- It is also called glycerine. It is a non-toxic compound which is sweet in taste. It is usually in liquid form which is odourless, viscous and colourless. It has antiviral and anti-microbial properties.
Due to its remarkable properties, it is primarily used in food and pharmaceutical industries.
Glycerose- The aldose and ketose (here, glyceraldehyde and dihydroxyacetone respectively) form a mixture equilibrium, which is called glycerose. This can be obtained from glycerol.
Mild oxidising agent like bromine water or Fenton’s reagent $\left[ FeS{{O}_{4}}+{{H}_{2}}{{O}_{2}} \right]$ or sodium hypobromite oxidises the glycerol which results the mixture called glycerose.
The reaction is given as,

Additional information:
Fenton’s reagent- It is a solution of hydrogen peroxide with ferrous ions. It is mostly used as the catalyst for oxidising contaminants in the water. Fenton’s reagent is used in organic synthesis of phenol from benzene as,
\[{{C}_{6}}{{H}_{6}}+FeS{{O}_{4}}+{{H}_{2}}{{O}_{2}}\to {{C}_{6}}{{H}_{5}}OH\]

Note: There are three reagents to produce glycerose from glycerol. Here, only one is shown, but the reactants are products are the same for all the reactions.
