Jatropha curcas hydroxylated and urethanated polymeric material – Preparation and characterization

Akintayo Cecilia Olufunke


Jatropha curcas oil was hydroxylated with formic acid in the presence of excess hydrogen peroxide to give polyhydroxylated oil with hydroxyl value of 170mgKOH/g. Through the hydroxyl group of the polyhydroxylated oil, urethane moieties were successfully appended on to the triacylglycerol to obtain the urethanated oil. The reactions were followed by both Infrared and nuclear magnetic resonance. Infrared analysis was performed on a Nicolet 380 Fourier-transform infrared (FTIR) spectrophotometer using NaCl cells. 1H-nuclear magnetic resonance (NMR) and 13C-NMR were obtained on a Bruker Avance 400 NMR spectrophotometer. Physico-chemical characterisation of the samples for iodine value (IV), saponification value (SV) and hydroxyl value (HV) were carried out titrimetrically. Thermal transitions of the products were studied on a differential scanning calorimeter (DSC). The grafting process, spectroscopic characterisation, film and solvent properties of the resulted product are hereby discussed.

Keywords: Polyhydroxyl, Urethanated, Jatropha curcas oil, Synthesis, Characterisation.
