Conversion 9-Methyl Octadecene to 1-Octadecanol
Abstract: The investigations
of methyl oleate (methyl 9-octadecenoate) to convert 1-octadecanol, has been
done. The conversion was carried out using ZSiA catalysts and fixed bed reactor
that was operated at 400, 450, and 500oC.ZSiA catalyst was prepared
by washing zeolite with aquadest, followed by dipping in HCl 2M solution,
adding Na 2 SiO 3 5% b/b, dipping in NH 4 Cl 2M, calcination at 500 o C under nitrogen with flow rate of 20
mL/min for 2 hours, oxydation under oxygen flow rate of 20 mL/min.
Characterization of the catalyst included determination of metal content using
AAS, acidity using gravimetric method, surface area using Gas Sorption Analyzer
NOVA 1000, and crystallinity using XRD. The fixed bed reactor was filled by
catalyst and heated up to 400 o C under hydrogen
flow rate of 20 mL/min. Then the feed (methyl oleate or methyl 9-octadecenoate)
in evaporator was heated up to 400 o C
under hydrogen flow rate of 20 mL/min. The reaction product was collected in
glass tube and analyzed using GC-MS. Catalytic hydrogenation of methyl oleate
produced 87,21% of 1-octadecanol as major product. 1-octadecanol product
decreased significantly by the increase of hydrogen flow rate from 20 to 60
mL/min and for 5 to 15 grams catalysts.
