| Summary: | SYNTHESIS OF DODECYLAMINE FROM PALM KERNEL OIL
(PKO) AS RAW MATERIAL FOR NYLON PRODUCTION
Indonesia’s palm oil industries are having a progressive development, as the
country has become the biggest palm producer across the globe. Palm kernel oil
(PKO) is the oil that extracted from the palm core/kernel that can be processed into
its derivative products. Almost 50% of PKO is still raw exported shows that the
utilization and processing of PKO is still lacking. Meanwhile, the development of
technology in processing PKO into renewable alternative materials as substitute
for petroleum-based products, such as nylon, is emerging nowadays.
PKO has its derivative product fatty acid methyl ester (FAME) as methyl laurate
that can be produced by transesterification of oil and fat from plant. FAME can be
distilled to achieve methyl laurate (C12:0). Methyl laurate can be turned into fatty
alcohol as dodecanol with hydrogenation process. Dodecanol reacted with NH3 gas
and cobalt silica-based catalyst. Product of this amination process is dodecylamine
that can be used for making nylon1212.
The result of hydrogenation does not show significant result with the addition of
water into the reactant. The conversion of methyl laurate is 96,9% and selectivity
of dodecanol is 50,7% that the reaction happened in mol ratio methanol : methyl
laurate : water is 15:1:1. The result of amination of dodecanol show that the higher
the temperature, the greater the conversion of dodecanol, but the selectivity to
dodecylamine decreases. Another factor that influences selectivity is H2 pressure,
which if too much pushes the reaction to form tridodecylamine and dodecane. The
operating conditions that produced the best results were in the form of 64%
dodecanol conversion and 24% dodecylamine selectivity with dodecane solvents at
150oC.
