| סיכום: | In Indonesia, solid rubber is the most common form of natural rubber (NR)
intermediates because it is easy to store and transport. However,
hydrogenation, a process aimed at improving the quality of NR by addressing its
vulnerability to environmental factors due to the presence of carbon double
bonds, is typically carried out under relatively mild conditions using latex
material. This study explores a biphasic hydrogenation approach using solid NR
dissolved in a solvent and a hydrogen source (hydrazine hydrate and hydrogen
peroxide) mixed in water. The choice of solvents, catalysts, and the
water-to-solvent volume ratio were examined for their impact on hydrogenation.
Characterization was conducted using Fourier Transform Infrared (FTIR) spectroscopy
as a qualitative indicator of hydrogenation. Meanwhile, Nuclear Magnetic
Resonance 1H-NMR spectroscopy is used to measure the degree of
hydrogenation. The results indicate that partial hydrogenation was successful
using toluene as a solvent and ethylene diamine tetra acetic acid diammonium
copper (Cu-EDTA) as a catalyst, with variations in water volume influencing the
degree of hydrogenation. A degree of hydrogenation of 7.69% was achieved using
15 mL of water. The thermal properties of hydrogenated NR remain comparable to
the original material, with improved heat resistance. This biphasic
hydrogenation method offers the potential to enhance the properties of NR in
various applications. |
