What is it about?
The Oxone® salt, a potassium stable triple salt containing potassium peroxy monosulfate (2KHSO5·KHSO4·K2SO4), is an oxidant agent and in recent years, reactions promoted by Oxone® have been widely reported, because of its’ ther- mal stability, water-solubility, incredibly cheap, less toxic ‘green’ nature, nonpolluting byproducts, and highest cost- effectiveness when compared to another oxidant agent. Therefore, Oxone® was applied as catalyst alternative to the catalysts already reported for esterification of residual oil of PFAD.

Why is it important?
Catalytic application of Oxone® salt was used in the present study for the esterification reaction of PFAD, as simple and mild method for biodiesel production. This protocol is advantageous as the esterification of PFAD, takes place under mild conditions, with maximum of > 90% con- version at 42 °C using a PFAD:ethanol molar ratio of 1:5 over a 12 h reaction time, without the need for pre-treatment of the catalyst.
Perspectives
The results obtained from this study indicate that esterifica- tion of PFAD using Oxone® may be a less expensive but promising alternative for production of sustainable fuels. However, further studies will be needed to assess its appli- cability in other oils for biodiesel purposes.
