Abstract

In this study, a natural type of zeolite, Clinoptilolite (CLI), is used as a support for TiO .First,TiO -supported heterogeneous 2 2 catalysts originated from the high temperature calcination of TiCl groups, which were thermally immobilized on clinoptilolite, were obtained. Powder-XRD and EDX analyzes showed that the oxide form of Ti-immobilized on dealuminated clinoptilolite were formed in the anatase phase, and the zeolite structure was preserved. As seen in TGA/DTA analyzes, this catalyst could be efficient and have high stability for many reactions. Second, the esterification reaction of 1-octanol with acetic acid is used as a reference reaction for this catalyst.
