We describe a novel, integrated multi-step process for the partial oxidation of alkanes to alcohols, ethers or olefins using O-2 as oxidant. The sequential transformations are (1) alkane bromination to alkyl bromide(s) and HBr, (2) reaction of this mixture with solid metal oxide (MO) to neutralize the HBr and to generate oxygenated products or olefins plus solid metal bromide, and (3) oxidation of the spent solid with 02 to regenerate the metal oxide and Br-2 for reuse.


The C-11-radioisotopic study of methanol conversion on V-MCM-41: The influence of methyl iodide on the transformation
Sarkadi-Priboczki, E.; Gucbilmez, Y.; Solmaz, A.; Balci, S.; Szelecsenyi, F.; Kovacs, Z.; Doğu, Timur (Elsevier BV, 2009-04-30)
The methanol conversion and a feasible methanol co-reaction with methyl iodide were studied on a vanadium incorporated MCM-41 type (V-MCM-41) mesoporous catalyst. which was prepared by a direct hydrothermal synthesis method. Adsorption/desorption as well as conversion derivates of radioactive methanol were easily followed by radioactivity detectors on V-MCM-41. The transformation and coreaction products were analyzed by a gas chromatograph equipped with Radio/FID detectors. The radiodetector was applied to ...
Mechanism of TAME and TAEE synthesis from diffuse-reflectance FTIR analysis
Boz, N; Doğu, Timur; Murtezaoglu, K; Dogu, G (Elsevier BV, 2005-02-28)
Diffuse-reflectance FTIR results obtained with tert-amyl-methyl-ether (TAME), ethanol, methanol, i-amylenes and mixtures of i-amylenes with alcohols supported a Langmuir-Hinshelwood type reaction mechanism involving adsorbed i-amylene molecules, which form a bridged structure between the adsorbed alcohols and the -SO3H sites of Amberlyst-15. Number of available sites involved in the adsorption of i-olefins is drastically decreased with an increase in alcohol concentration. The reaction rate model, which was...
Selective oxidation of propylene to propylene oxide using combinatorial methodologies
Miyazaki, T; Ozturk, S; Onal, I; Senkan, S (Elsevier BV, 2003-06-30)
Direct oxidation of propylene by oxygen to propylene oxide (PO) has been studied through the application of the techniques of combinatorial catalysis. Catalytic materials containing single and binary metal components were prepared by impregnating standard gamma-Al2O3 pellets. In the first stage, 34 single component catalytic materials at three different metal loading levels were prepared and screened for PO activity and selectivity using array channel microreactors and mass spectrometry. Experiments were co...
A novel asymmetric synthesis of highly enantiomerically enriched norbornane-type diamine derivatives
BOLM, CARSTEN; SCHİFFERS, INGO; ATODİRESEİ, IULİANA; Özçubukçu, Salih; RAABE, GERHARD (Royal Society of Chemistry (RSC), 2003-01-01)
The simple and highly enantioselective methanolysis of norbornene dicarboxylic acid anhydride mediated by quinidine leads to the corresponding cis-monomethyl ester with 98% ee. By means of selective ester epimerization, followed by Curtius degradation of the intermediate trans-diacyl azide, two optically active norbornane-type diamines are obtained as their hydrochloric salts. Liberating the amine with an excess of triethylamine in situ and subsequent derivatization affords potential C-1-symmetric ligands f...
A new and efficient chemoenzymatic route to both enantiomers of alpha '-acetoxy and alpha '-hydroxy-alpha-methoxy cyclic enones
Demir, Ayhan Sıtkı; Caliskan, Z; Aydin, AE; Bicer, I (Elsevier BV, 2006-03-06)
A chemoenzymatic synthesis of both enantiomers of the pharmacologically interesting alpha'-acetoxy and alpha'-hydroxy-alpha-methoxy cyclic enones starting from alpha-hydroxy cyclic enones is described. Protection of 1,2-diketones, manganese(III) acetate-mediated acetoxylation followed by enzyme-mediated hydrolysis of alpha'-acetoxy enones gives acetoxy enones 3a-d and hydroxy enones 4a-d with high enantiomeric excesses (up to 99%) and good yields. The transesterification of rac-4b in the presence of DMAP af...
