Abstract:

Ruthenium(III) acetylacetonate was employed for the first time as homogeneous catalyst in the hydrolysis of sodium borohydride. Ruthenium(III) acetylacetonate was not reduced by sodium borohydride under the experimental conditions and remains unchanged after the catalysis, as shown by FT-IR and UV-Vis spectroscopic characterization. Poisoning experiments with mercury, carbon disulfide or trimethylphosphite provide compelling evidence that ruthenium(III) acetylacetonate is indeed a homogenous catalyst in the hydrolysis of sodium borohydride. Kinetics of the ruthenium(III) acetylacetonate ca

Abstract:

A method for the preparation of submicron, monodispersed, spherical particles of aluminum hydrous oxide has been developed. The method consists of the hydrolysis of aluminum acetylacetonate in alcoholic solution by the direct addition of a base at room temperature. The effects of the process parameters including temperature, solvent, type and concentration of base, aluminum acetylacetonate concentration, and stirring time are examined as well as the process reproducibility, particle composition and particle stability. Results obtained have shown that monodispersed particles can be formed with

Abstract:

Amine boranes have recently been considered as solid hydrogen storage materials with high capability of hydrogen storage. Dimethylamine borane is one of the promising amine boranes with high theoretical gravimetric capacity of 16.9 wt%. Dimethylamine borane can undergo dehydrogenation only in the presence of a suitable catalyst at moderate temperature. In this project, throughout the dehydrogenation of dimethylamine borane (DMAB), the catalytic activity of ruthenium(III) acetylacetonate was examined for the first time. During the catalytic reaction, formation of a new in-situ ruthenium(II) s

In molecular magnetism, rational design and serendipity have played complementary roles in the synthesis of complexes which display a breadth of interesting physical characteristics.

The inherent physical properties of these complexes has already afforded molecules which can behave as single‐molecule magnets, singlechain magnets, single‐ion magnets, magnetic

Abstract:

Symmetric nonaqueous redox flow batteries (RFBs) use negative and positive battery solutions of the same solution composition to operate at high cell voltages. This research effort targets these systems since they offer performance improvements derived from using nonaqueous systems and symmetric active species. Nonaqueous solutions permit significantly higher cell voltages than state-of-the-art aqueous RFBs and symmetric active species chemistries reduce the required complexity of cell reactors. Both performance advantages correspond to significant cost improvements beyond already commercially

Abstract:

Polyethylene (PE) is one of the most popular polymers used in daily life. However, saturated hydrocarbons cannot absorb the energy of light reaching to earth, so degradation process is rather slow which in return cause disposal problems. On the other hand, it was observed that in presence of oxygen and impurities in the polymer matrix, degradation can be rendered to shorter time intervals. This study covers investigation of effect of three different additives in UV induced oxidative degradation of polyethylene.

Abstract:

Acetylacetone (AcAc) exists as a mixture of enol and keto tautomers. Besides providing a good example for the study of tautomerization, it is a model system for investigating intramolecular hydrogen bonds in its enol form. Trapping AcAc in the soft para-Hydrogen (pH2 ) environment brings out new opportunities to investigate its properties. Infrared spectra of the samples give a good characterization of the two stable enol and keto tautomers. The keto/enol ratio in solid pH2 is found to be higher than in other matrices.

Every year continue being up to 5~10% of the rate of increase. In addition, the photocatalytic application of the fibre. The photocatalytic application of TiO2 shows strong correlation with its particle size and crystal property. Therefore, the investigation of preparation on the TiO2 synthesis as well as the crystal phase evolution of the TiO2 product becomes very important. In general, TiO2 synthesis used precursors for the tita

Abstract:

Using a hydrogen donor and a catalyst for upgrading and increasing oil recovery during in situ combustion is a known and proven technique. Based on research conducted on this process, it is clear that widespread practice in industry is the usage of tetralin as a hydrogen donor. The objective of the study is to find a cheaper hydrogen donor with better or the same upgrading performance. Decalin (C10H18) is used in this research as a hydrogen donor. The experiments have been carried out using field oil and water saturations, field porosity and crushed core for porous medium. Four in situ combust

Abstract:

碩士<br>中原大學<br>化學研究所<br>106<br>The fascinating tautomerization process involving hydrogen migration of acetylacetone (denoted as Acac) has drawing much research attention over the past years. This microscopic molecular level tautomerization process will result in the macroscopic ensemble Keto‒to‒Enol equilibrium. In order to have a global understanding of the Acac tautomerization, the nuclear magnetic resonance (NMR) technology was used on both the microscopic electron cloud investigation (such as chemical shift observation) and the macroscopic ensemble average phenomenon of spectra themself.

Abstract:

Gas phase extraction using organic ligands has been gaining interest because it eliminates many of the problems encountered in conventional mineral processing methods. This process was successfully used to extract iron using the ligand acetylacetone from Fe2O3 in a fluidized bed reactor, with above 80% extraction being achieved after four hours for some experimental conditions. The extraction was shown to be dependent on temperature, ligand flow rate and the surface area available for reaction, with extraction increasing as each of the variables was increased. Chrome could not be extrac

Abstract:

Fly ash is a coal waste produced as a result of coal combustion in coal fired power plants and it is considered as a potential source of aluminium because it contains 14.8-31 wt% aluminium(III) oxide in amorphous and mullite phases depending on the coal type. Mullite is a crystalline structure formed by aluminium(III) oxide and silicate. The extraction of aluminium from a mixture of 31 wt% aluminium(III) oxide and silica as well as from fly ash collected from Eskom, Kendal Power Station using acetylacetone has been studied. A mixture of 31 wt% aluminium(III) oxide and silica was prepared
