Description

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.
