Density functional theory study of the ethylene epoxidation over Ti-substituted silicalite (TS-1)
The mechanism of ethylene epoxidation with hydrogen peroxide over Ti-substituted silicalite (TS-1) catalyst was investigated by using both the cluster and embedded cluster approaches at the B3LYP/6-31G(d) level of theory. The complete catalytic cycle was determined. The epoxidation of ethylene consists of three steps. First, the chemisorption of H2O2 at the Ti active site forms the oxygen donat...
متن کاملSynthesis of 2,3-Butanedione over TS-1, Ti-NCl, TiMCM-41, Ti-Beta, Fe-Si, Fe-Beta and VS-1 Zeolites
The purpose of this work is the synthesis of 2,3-butanedione (diacetyl) by selective oxidation of 2-butanone (methyl ethyl ketone) in the presence of O2 and H2O2 30% as oxidants. All the tests were performed over several selective oxidation zeolite catalysts, synthesized and characterized in our laboratory. Introduction 2,3-Butanedione or diacetyl, a flavor compound having a distinct buttery ch...
متن کاملThe epoxidation of limonene over the TS-1 and Ti-SBA-15 catalysts.
Limonene belongs to a group of very important intermediates used in the production of fine chemicals. This monoterpene compound can be obtained from peels of oranges or lemon which are a (biomass) waste from the orange juice industry. Thus, limonene is a renewable, easy available and a relatively cheap compound. This work presents preliminary studies on the process of limonene epoxidation over ...

متن کاملCorrosion Characteristics of a - Ti and Ti 2 Cu Composing Ti - Cu Alloys
A series ef binary Ti-Cu alloys containing 5-20 mass% Cu was prepared, and the corresien behavior of a-Ti and Ti2Cu composing the Ti-Cu alloys were examined based on the anodic polarization curves and released iens in O.9% NaCl and 1% lactic acid solutions. In both selutions, the Ti-Cu alloys showed the same anodic polarization curves as titanium in the conditien below 1.4 V. Hewever, precipita...
