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.

Protocols

In this study, SPME was used for the analysis of free fatty acids in Parmesan cheese using a 65 μm Carbowax/divinylbenzene (DVB) SPME fiber. Headspace extraction of the cheese sample was conducted at 65 °C for 15 minutes and analyzed by GC with FID detection. SPME is ideal for analyzing the volatiles associated with solid food samples. The phase chemistry of the Nukol GC column provides excellent peak shape of acidic compounds.
