description: Rubber seed oil (RSO) (Hevea brasiliensis) was extracted from rubber seeds by  chemical means. The effect of temperature on the oil yield was investigated. The  experiment suggested that the maximum yield of the oil occurs at 60 °C. This is a  result of the proximity to the boiling point of n-hexane, which is about 68 °C.  Epoxidized and hydroxylated RSOs were further synthesized by performic acid  generated in situ by the reaction of formic acid with 30% hydrogen peroxide. The  physiochemical properties of the epoxidized rubber seed oil (ERSO) and  hydroxylated rubber seed oil (HRSO) were determined. A separate study was also  carried out on castor seed oil (CSO). The improved products were characterized with  respect to their configuration and properties. Spectroscopic analysis was carried out  on the oil base stocks (RSO, CSO, ERSO, and HRSO). All of the experimental  findings were compared with one another. The lubricating properties of CSO and  HRSO are further studied as a result of their common hydroxyl nature to ascertain  their suitability as a lubricant base. Both oils can be categorized as a nondrying oil  with saponification values of 179.52 and 255.25 mgKOH/g, respectively, and as such  possess advantageous properties for industrial application. When compared to one  another, HRSO appears to be a more effective choice as a lubricant base. This is  because of its higher viscosity index of 380.65. The outcomes of this study indicate  that hydroxylated and epoxidized RSO with high oxirane content can be synthesized  concurrently by one-pot multistep reactions.
