The zinc ferrite obtained by oxidative precipitation method as a catalyst in n-butanol conversion

This paper presents the results of catalytic properties of n-butanol conversion of the zinc ferrite obtained by oxidative precipitation method. The zinc ferrite showed good dehydrogenating activity but also catalyzed consecutive bimolecular condensation of emerged aldehyde particles into symmetrical ketone. The zinc–iron oxide of spinel structure was prepared from ferrous sulfate, which forms as a waste during the titanium dioxide production. The X-ray diffraction methods (XRD, XRF) were used in determining the structure and composition of obtained zinc ferrite, while thermogravimetry (TG–DTG), and differential thermal analysis (DTA) were used in the study of thermal transformations of zinc spinel in air.
