Studies on the epoxidation of rubber (Hevea brasiliensis) seed oil, a renewable source with formic acid was performed in the presence of 30% hydrogen peroxide at a of temperature 40, 50, 60, 70 °C. The process is favoured by an increase in temperature forming a product with high oxirane content which is as a result of mole ratios of formic acid and hydrogen peroxide. Products of high oxirane content are commercialy viable in the production of polyvinyl chloride (PVC). Natural rubber and other products can be obtained from this in- situ technique. Studies in this research shows that the rate of epoxidation increases with an increase in temperature.Oxirane values of 2.30, 3.62 and 4.73 for the various temperature. However high oxirane content of 6.22 was obtained at 70 °C which is in line with literature. FTIR analysis was also carried out on the epoxidized rubber seed oil which shows the peaks of oxirane cleavage.
