Description

Application

Octanoic acid can be used as a reactant:

• In the SnO/TiO₂ catalyzed esterification with polyols to synthesize lubricating esters.
• To synthesize amides using primary and secondary amines in the presence of a biocatalyst.

It can also be used as a catalyst for oxidizing sulfides into their corresponding sulfoxides and sulfones with H₂O₂ as the oxidant.
