Polyol, a raw material of polyurethane, has successfully been produced from a renewable resource namely RBD palm oil. This polyol was made by firstly adding a peroxyacetic acid formed in situ from H2O2 and CH3COOH with H2SO4 as cataliyst into RBD palm oil to form epoxidized RBD palm oil. The epoxidized palm oil then was added to a mixture of methanol (MeOH), isopropanol (IPA), and H2SO4 for 2 hours at 60oC so that palm oil-based polyol was formed. The main equipment used in this research was a 500 mL three necked flask, equipped with a reflux condeser, thermometer, water bath and magnetic stirrer. The product was analysed using a titration method and Infra Red (IR) Spectroscopy. It was obtained that the produced palm oil-based polyol has a value of hydroxyl number of 150-209 mg KOH/g sample and a viscosity of 740.777 cP.
