Abstract
Rubber seed oil as a non-edible oil is a potential cheap source for biolubricant feedstock. In this study, the oil is modified to improve the inherent properties limiting its applicability. Preparations of samples were carried out by epoxidizing the oil, simultaneously opening the oxirane ring and transesterification, and finally acetylation. A significant decrease was observed in the iodine value after epoxidation. The prepared products from each stage showed viscosities greater than ISO VG 46 requirement for hydraulic oils and are within the range of ISO VG 150 and ISO VG 220 for extreme pressure gear oils and slide way oils, respectively. Their relatively high viscosities at high temperature and high viscosity indices make them suitable for high temperature and wide temperature range application. Their low-temperature application prospects are fairly good due to their relatively high pour point values. Hence, they require pour point depressant to enhance their low-temperature applicability.
