General description

Hydroxyacetone (Acetol) is important for the manufacture of polyols, acrolein, dyes and skin tanning agents. It undergoes asymmetric reduction to yield (R)-1,2-propanediol in the presence of microbial cell catalyst.

Application

Hydroxyacetone was used to study aerobic oxidation of glycerol and propanediol over metal oxide supported gold nanoparticles in methanol.
