Abstract

Response surface methodology (RSM) with central composite rotatable design (CCRD) was used to optimize the hydrogenation parameters of liquid natural rubber (LNR) in hydrazine hydrate (HH) and hydrogen peroxide (H2O2) system in the presence of selenium as catalyst. The parameters studied in this research were the mole ratio of HH:LNR (1.25-2.25), mole ratio of H2O2:LNR (1.25-2.25), reaction temperature (40-80°C) and reaction time (4-8 h). Based on the data obtained, hydrogenation of LNR fit the quadratic model. This quadratic model had the determination coefficient (R2) of 0.9596 that showed high correlation between the actual hydrogenation percentages and the predicted percentages. Based on the 3D surface plot, the reaction temperature played an important role in the hydrogenation of LNR. The optimum conditions for hydrogenation of LNR in hydrazine hydrate/hydrogen peroxide system in the presence of selenium catalyst were as follows: mole ratio of HH:LNR of 1.50, mole ratio of H2O2:LNR of 2.00, reaction temperature of 53.34°C and reaction time of 5.21 h that yielded 68.98% of hydrogenated product. Quadratic polynomial equation that was obtained from RSM is useful in preparing HLNR with desired hydrogenation percentages.
