Abstract

Hydroxy-ether-POo (80% of yield) was synthesised through oxirane cleavage of epoxidized palm olein (EPOo) using alcoholysis process. An optimum oxirane cleavage has been obtained with 99.2% yield using sulphuric acid 3% v/wt at 80°C for 30 min. The proton-nuclear magnetic resonance (1H-NMR) spectrum of hydroxy-ether-POo showed the presence of proton peak attached to the carbon of ether (3.2, 3.5 ppm) and proton of hydroxy (4.8 ppm). The carbon-nuclear magnetic resonance (13C-NMR) spectrum of hydroxyl-ether-POo showed the presence of carbon peak bonded to hydroxyl (75 ppm) and carbonyl carbon on ether (72 ppm). While, kinematic viscosity of Hydroxy-ether-POo was 234.4 cSt (40°C) and 28.1 cSt (100°C) with the viscosity index of 156.
