Abstract

Di-hydroxy-POo (70% of yield) was synthesised through oxirane cleavage of epoxidized palm olein (EPOo) by using continuous and batch hydrolysis process. Both hydrolysis processes obtained an optimum oxirane cleavage yield (97.2%) by using perchloric acid 3% v/wt for 90 min (continuous process) and 75 min (batch process). The presence of stretching vibration broadband peak of hydroxyl at wavenumber 3429 cm-1 shown on the Fourier transformation infra-red (FTIR) spectrum, indicate formation of polyols compound. The carbon-nuclear magnetic resonance (13C-NMR) spectrum of di-hydroxy-POo showed the presence of carbon peak bonded with hydroxyl (74.5 ppm). The proton-nuclear magnetic resonance (1H-NMR) spectrum of di-hydroxy-POo showed the presence of proton peak attached to the carbon of polyols (3.4 ppm) and proton of hydroxyl (4.6 ppm). Kinematic viscosity of polyols product (110.7 mgKOH/g oil) were 1435.2 cSt (40°C) and 55.2 cSt (100°C) with the viscosity index of 78.
