STUDI SPEKTROSKOPI INFRA MERAH KATALIS KOBALT (II) YANG DIAMOBILISASI PADA SILIKA MODIFIKASI
Abstract: A Synthetic process
has been carried out for preparation of cobalt (II) grafted on modified silica
and applied in transesterification
reaction. First step
was a modification
of silika support
with anyline and
bor trifluoride in toluene at room temperature. An
acetonitrile solution of cobalt chloride then was added with the modified
silika and refluxed at 70 oC for 2 hours. Product obtained was characterized
with Fourier Transform Infra Red (FT-IR). In general it
can be concluded
that the grafted
product showed the
formation of anylinium
species wich then consumed during grafting process due to
its reaction with cobalt cation (FTIR analysis).
