Application

Heptanoic acid can be used:
  • For esterification with glycerol to synthesize a triacylglycerol called as triheptanoin or trienanthoin.
  • To synthesize 1-hexene via decarbonylation reaction by using platinum nanoparticles supported on carbon.
  • To synthesize 7-tridecanone by ketonization in the presence of MnO2/CeO2 or ZrO2 catalysts supported on the surface of alumina.
