- W3085893058 abstract "In this study, synthesized polyols from refined palm oil, one of the ingredients in producing polyurethane CPU) foam, were investigated. The effects of reaction time, pH and type of solvents used on the properties of the polyols were characterized by using gas chromatography massspectrometry (GC-MS), fourier transform infrared (FTIR) spectroscopy and gel permeation chromatography (GPC). Further studies were carried out by using the synthesized polyols incombination with other chemicals for PU foam formation. The characterizations of the PU foamswere performed through chemical, morphological and thermal analyses. The results showed thatthe polyols were synthesized successfully from refined palm oil by using epoxidation and thehydroxylation process. 50 % of the unsaturated fatty acids in the refined palm oil were convertedto saturated fatty acids and hydroxyl compounds as the reaction time increased up to five hours.However, the chemical contents in the polyols did not show significant changes as the pH valueincreased from pH 3 to pH 7. Using different types of solvent in the process showed that thehydroxyl content of the polyols ranged between 57 to 69 mg KOHl g, with M w in the range of15325 to 19320 g mOrl. The results also revealed that not all the synthesized polyols weresuitable for PU foam formation. It is recommended that the minimum hydroxyl content andmolecular weight of the synthesized polyol required for PU foam formation is 69 mg KOHl gand 19320 g morl respectively. The properties of PU foam are highly dependent on the polyoland the water (blowing agent) content." @default.
