Rubber seed though not common known is very rich in its oil yield and over time its importance is becoming more prominent. Bleaching in the natural sense is relative to the removal of impurities from the oil or material. In this research work, Rubber seed oil was bleached using bentonite clay and Ibeshe clay at 0.5M, 1M and 2M concentrations of Hydrochloric acid. Physiochemical properties as well as spectroscopic analysis such as FT-IR and XRD analysis were carried out and aided in obtaining the bleaching efficiency of both clays. The FT-IR results displayed a visible change in the oil after it was bleached with Ibeshe clay but still retained most its functional group when bleached with bentonite clay. At 2M concentration of the acid, the oil bleached with bentonite showed 53% while with Ibeshe clay it remained at 16%. This summarizes that Ibeshe clay has little to no effect on bleaching performance.

In this research, the polyurethane adhesive based on modified rubber seed oil with toluene diisocyanates was successfully synthesized in presence of DBTL catalyst. The chemical structure of modified rubber seed oil was characterized by 1H-NMR. The suitable reaction time of the polyurethane adhesive synthesis was 4h by providing with FT-IR technique. The effects of NCO index and chain extender (1,4-butane diols) content in adhesive formulation as well as cure temperature were also studied by leather to leather on adhesion peel strength. It was found that the higher NCO index or chain extender content gave the higher adhesion of substrate. The cure temperature of adhesive at 70 °C gave the better peel strength than that at 30 °C during 24 h.

Epoxidation of rubber seed oil was carried out using a peroxyacid generated in situ from glacial acetic acid and hydrogen peroxide to produce epoxidized rubber seed oil. The maximum relative conversion to oxirane of 88 % could be obtained at 60 °C after a reaction time of 7 hours. The presence of oxirane ring of epoxidized rubber seed oil was confirmed by fourier transform infrared spectrometer (FT-IR) and proton nuclear magnetic resonance (1H NMR) spectra analysis which displayed a disappearance of double bonds peak in rubber seed oil and an existing of epoxide ring peak in epoxidized rubber seed oil.

In this study, different characteristics of sustainable renewable biodiesels (those have a high potential of their production worldwide and in India) were compared with the characteristics of neat diesel to determine optimistic biodiesel for the diesel engine at 250 bar spray pressure. Optimistic fuel gives a comparatively lower level of emissions and better performance than other selected fuels in the study. Rubber seed oil methyl ester was investigated as an optimistic fuel among the other selected fuels such as sunflower oil methyl ester, neem seed oil methyl ester, and neat diesel. To enhance the performance characteristics and to further decrease the level of emission characteristics of fuel ROME, further experiments were conducted at higher spray (injection) pressures of 500 bar, 625 bar, and 750 bar with varying ignition delay period via varying its spray timings such as 8°, 13°, 18°, 23°, 28°, and 33° before top dead center. Spray pressure 250 bar at 23° before top dead center was investigated as an optimistic operating condition where fuel rubber seed oil methyl ester gives negligible hydrocarbon emissions (0.019 g/kW h) while its nitrogen oxide (NOX) emissions were about 70% lesser than those observed with neat diesel, respectively.
