Abstract

 

ABSTRACT
Mesoporous silica has attracted rapidly growing attention in catalysis. In this work, mesoporous
silica was synthesized by using CTAB surfactant and then modified by AlCl3. Such material
was used as support for Cu(II)--acetonitile complex and applied in transesterification of frying
oil. The XRD pattern of the obtained silica confirms the availability of chracteristic peak on
silica surface while its TEM exhibits the uniformity of nanochannel of the mesoporous silica.
The particle size of silica support has become smaller after grafting process showed by SEM
images. FT-IR spectra of the materials indicated that the Cu(II) grafted on the mesoporous
silica was in the form of its acetonitrile complex. Supprisingly, the Cu loading the grafted
catalyst was found to be very high. That was 21%, when the catalyst applied on
transesterification of the examined frying oil the amount of total methyl ester yielded were of
65%.
Keywords: mesoporous silica, AlCl3, Cu(II)-acetonitrile complex, transesterification
