Abstract: This study was carried out to synthesize waste cooking oil (WCO)-based polyol for polyurethane via one-pot epoxidation and hydroxylation reaction. WCO was first pretreated prior to be used to synthesize WCO-based polyol. The effect of concentration of hydrogen peroxide (H2O2) as oxidant was observed using FTIR and GC-MS intruments and by determination of hydroxyl value (OHV) iodine value (IV). FTIR spectra of WCO-based polyol prepared using 35% hydrogen peroxide shows the formation of OH absorption peak as proof that the reaction successfully converted double bonds in WCO structure into OH. This supported by the increase in OHV from 5.030 (WCO) up to 229.32 mgKOH/g (WCO-based polyol using 35% H2O2). It was found that the OHV increased as the concentration of H2O2 used increased. GC-MS analysis of WCO-based polyol gave the molecular weight value of 597.3g/mol and functionality calculated is 2.44. This study showed that the chosen reaction is suitable for synthesis of WCO-based polyol and WCO exhibit promising potential as raw material for flexible polyurethane.
