Abstract

Reactions of polyol with a variety of functional groups to produce polymeric materials are well documented in both academic and industrial research environments. Current trends to produce polyols towards green technology have catalyzed the research on renewable resources such as vegetable oils to replace petrochemical-based materials. The introduction of hydroxyl group (OH), via. transamidation of diethanolamine has successfully converted the Refined Bleached Deodorized Palm Oil (RBDPO) into polyol. RBDPO was reacted with diethanolamine and refluxed at 110°C for 5 h without any catalyst and solvent, resulted the establishment of diethanolamide with high hydroxyl number. It was proven by FTIR study where the sample spectrum underwent significant changes, particularly in the gradual appearance of the broad peak O-H band at around 3301 cm-1. Another significant change was the appearance of the peak C = O stretching at around 1619 cm-1 and C-N at around 1049 cm-1. These changes indicated the formation of diethanolamide. The synthesized palm oil-based polyol has hydroxyl number of 254.20 mL NaOH/g with fewer amounts of acid numbers which is 3.60 mL NaOH/g. This study showed that polyols made from RBDPO-diethanolamine reactions can be used as an alternative source of polyols in polymer synthesis.
