Production Of Bassia (bassia Longifolia) Oil-based Polyol Via Epoxidation And Ring Opening

Vegetable oil-based products and derivatives have emerged as popular alternatives for petrochemical-based materials due their more environmental friendly feature. Over the years, extensive studies have been conducted on bassia (Bassia longifolia) oil as it contains high degree of unsaturated fatty acids which is a crucial characteristic in producing high performance materials. In this study, bassia oil-based polyol was prepared by ring opening epoxidation and followed by hydroxylation to produce polyol from Bassia oil. The reaction hydroxylated epoxidized oil with toluene diisocyanate (TDI) to make polyurethane for further application. Epoxidation of Bassia oil measured using oxirane oxygen content (OOC) test of value 4.114% OOC which show optimum epoxidation reaction at six hour of reaction time. Acid value for epoxidized, and hydroxylated Bassia oil was recorded at 3.40 mg KOH/g and 2.58 mg KOH/g respectively.Analysis was performed using spectroscopic techniques, such as FTIR and1H NMRfor the confirmation of polyol. FTIR showed bands of OH and urethane groups at 3363 cm-1 and 3347 cm-1 respectively while NMR spectroscopy reveals resonance peaks of protons and carbons attached to the polyurethane.
