Sytnhesis and characterization of nano zinc borate and its usage as a flame retardant for polymers
Baltacı, Berk; Bayram, Göknur; Department of Chemical Engineering (2010)
The objectives of this study are to synthesize sub-micron sized zinc borate and to use them with other flame retardant additives in poly(ethylene terephthalate) (PET) based composites. The study can be divided into two parts. In the first part, it was aimed to synthesize sub-micron sized zinc borate (2ZnO.3B2O3.3.5H2O) with the reaction of zinc oxide and boric acid. For this purpose, low molecular weight additives or surfactants were used in the syntheses to prevent the agglomeration and to decrease particl...

Dimethyl ether synthesis over novel mesoporous catalysts
Tokay, Kenan Cem; Doğu, Timur; Department of Chemical Engineering (2008)
Due to overconsumption, fossil reserves are rapidly being depleted and various sources predict that they will not last until the end of 21st century. Moreover, the increase in the rate of global warming and the polluting matter emitted by the vehicles consuming fossil fuels has increased the search for renewable and clean energy sources. Alcohols and ethers, which contain fewer pollutants and have better burning properties, are commonly thought among clean fuel alternatives. Among the potential clean energy...
Synthesis of furopyrrolone and furopyridazinone derivatives: a new class of compounds
Karahan, Emrah; Balcı, Metin; Department of Chemistry (2011)
Furopyrrolone has a bicyclic structure consisting of furan and a pyrrolone ring. It is isoelectronic with isoindolinone which is also a heterocyclic organic compound. It has a bicyclic structure, consisting of a benzene ring fused to a five-membered nitrogen containing pyrrolone ring. Pyrrolones, pyrrolidines, pyrrolidinones, pyridazines and pyridazinones are precursors to many pharmaceuticals. In this project we developed new synthetic procedures leading to the synthesis of furopyrrolone derivatives. To do...
