Propylene epoxidation on CoO and Li promoted CoO catalysts: a density functional theory study
Gezer, Miray; Önal, Işık; Department of Chemical Engineering (2014)
Propylene oxide is a significant intermediate chemical which has many derivatives used as raw materials in many industries such as automobile, cosmetic, medicine etc. However, its current production methods, chlorohydrin process and hydroperoxide process, are not preferred since they are economically and environmentally disadvantageous. Considering these negative effects, heterogeneous catalyst for direct propylene epoxidation is still being investigated. With an objective of filling this catalyst gap in th...
Catalytic reaction of propylene to propylene oxide on various catalysts
Kalyoncu, Şule; Önal, Işık; Şeker, Erol; Department of Chemical Engineering (2012)
Throughout this thesis work, various catalysts were investigated with combinational approach to develop highly active and selective novel catalysts for direct epoxidation of propylene to PO using molecular oxygen. The promoted and un-promoted silver (Ag), copper (Cu), ruthenium (Ru), manganese (Mn) mono and multimetallic catalytic systems over different silica supports were prepared via sol-gel method and incipient wetness method. In addition to support effect, the effects of different promoters on the cata...
Catalytic partial oxidation of propylene on metal surfaces by means of quantum chemical methods
Kızılkaya, Ali Can; Önal, Işık; Department of Chemical Engineering (2010)
Direct, gas phase propylene epoxidation reactions are carried out on model slabs representing Ru-Cu(111) bimetallic and Cu(111) metallic catalyst surfaces with periodic Density Functional Theory (DFT) calculations. Ru-Cu(111) surface is modelled as a Cu(111) monolayer totally covering the surface of Ru(0001) surface underneath. The catalytic activity is evaluated following the generally accepted oxametallacycle mechanism. It is shown that the Ru-Cu(111) surface has a lower energy barrier (0.48 eV) for the s...

Reaction of propargyl aldehydes with hydrazinium salts: synthesis of ferrocenyl and Phenyl substituted pyrazoles
Pınar, Ayşe Nur; Zora, Metin; Department of Chemistry (2008)
Pyrazoles have been focus of a large number of investigations in the design and synthesis of novel biologically active agents that show remarkable medicinal activities. Although pyrazoles have been studied for over a century as an important class of heterocyclic compounds, they still continue to attract considerable attention due to the wide range of medicinal activities they possess. Recent studies have shown that combination of a ferrocenyl unit with structural features of pyrazoles can lead to products w...
