Çeşitli Katyon Değiştirilmiş ve Sütunlanmış Artvin Bentonitlerinin Karakterizasyonu ve Seçilmiş Bir Organik Reaksiyonda Katalizör Olarak Kullanılmaları
Öz
Bu çalışmada Artvin ham bentonitinin, bazı metal katyonları (Fe3+ ve Cu2+)
değiştirilmiş ve Fe- ve Al-sütunlanmış türevlerinin benzaldehitin 2,3-bütandiol
ile asetalleşme reaksiyonundaki katalitik aktiviteleri araştırıldı. Bu
katalizörlerin yapısal ve fizikokimyasal özellikleri X–ışınları toz kırınım
(XRD), taramalı elektron mikroskobu (SEM), Fourier transform infrared
(FTIR), ve yüzey alanı ölçüm teknikleri
yardımıyla aydınlatılmıştır. Cu-bentonit ve Al sütunlu-bentonit katalizörlü
reaksiyonlarda verimin çok az olduğu buna karşın Fe-bentonit ve Fe-sütunlu
bentonit katalizörlerinin kullanıldığı tepkimelerde ise sırasıyla % 60 ve % 63
verimle asetalleşme reaksiyonu gerçekleştiği tespit edilmiştir. Bu çalışma
ülkemizin önemli yerli kaynaklarından birini teşkil eden Artvin bentonitinin
modifiye edilmesiyle organik reaksiyonları katalizleyebildiğini ve bu ürünlerin
küçük ölçekte ve endüstriyel proseslerdeki reaksiyonlar için
kullanılabileceğini ortaya koymuştur.

Characterization of Various Cation Exchanged and Pillared Artvin Bentonites and Their Use as a Catalyst in a Selected Organic Reaction
Öz
In this study, the catalytic
activities of raw, some metal cations exchanged (Fe3+ and Cu2+)
and Fe- and Al-pillared Artvin bentonite samples as a catalyst for
acetalization reaction of benzaldehyde with 2, 3-butanediol were investigated.
The structural and physicochemical properties of clay samples were examined by
using X-Ray powder diffraction (XRD), scanning electron microscope (SEM),
Fourier Transform infrared (FTIR) and surface area measurement techniques. The
yield of this organic reaction in the presence of Cu-bentonite and Al-pillared
bentonites were found as very low whereas Fe-bentonite and Fe-pillared
bentonite catalysts showed 60 and 63% yield in acetalization under same
conditions, respectively. This study showed that modified Artvin bentonite
samples which is the one member of Turkey’s important local and natural sources
can be used as catalyst in the selected organic reaction and their utilization
in industrial process reactions in small scale.
