Palm olein ozonation as a renewable resource: spectroscopic analysis for monitoring the degree of saturation

Abstract

The manufacturing of organic compounds by environmentally-friendly methods has been intensively reexamined in recent years. Several excellent methods have been devised to produce organic compounds from renewable resources. The ozonation is one of the high active oxidation methods which lead to producion of organic compounds by the breaking of double bonds. Palm olein as a renewable source is subjected to the ozonation process to break the double bond which leads to the formation of two carbonyl groups as well described by Criegee mechanism. The monitoring of the degree of saturation was obtained by the Fourier transform infrared spectroscopy (FTIR) by observing the change in function groups as a result of ozone consumption and heat of reaction. The reaction time was 2 hrs at different temperatures and without any solvent or participating catalyst. The complete cleavage of a double bond occurred at 150 °C temperature of reaction.
