- W2298913791 abstract "(a)The New Saccharin Salts Used in the Catalytic Acylation Reaction and Recycling We had successfully synthesized and purified the salt made of DMAP and saccharin. It’s surprising to discover that DMAP-salt and the other salts have the similar structure, and they can used in the catalytic esterification reaction of the alcohol. Conversion yield percentage and reaction time compared with the literature data, the overall efficiency of the reaction about 30 times. However, the reaction without adding solvents and bases can be carried out at room temperature. This discovery is based on the crystallization for series of saccharin and saccharin’s compounds. In the thesis, we improve the disadvantages of catalysts recycling. The non-polar solvents can soluble the acylation product, but catalyst can’t. We use catalyst insoluble characteristics through the centrifuge can easily recycle catalysts. Furthermore, the recycle-easy catalysts are based on concept of modern green technology. (b)High Efficient Bis(fluoro-ponytailed) Bipyridine Ruthenium complexes containing Tetrabutylammonium for Dye-Sensitized Solar Cells We used particular by designed bis(fluoro-ponytailed) bipyridine binding with rethenium. After purification of crude dye by column chromatography, the product was analyzed and spectroscopically characterized by multi-nuclei NMR (1H, 19F and 13C), FTIR and FAB. We synthesis of the CT series of dyes containing different tetrabutylammonium numbers had H1TBA3 and H3TBA1 two types. Dye molecules with different tetrabutylammonium numbers of photoelectric conversion efficiency. UV-vis, CV and other instruments measured results compared with the N719. We study the different tetrabutylammonium numbers of the dye in the optical, electrochemical and photoelectric conversion efficiency." @default.
