synthesis of sulfides from alcohols and thiols in solvent-freeconditions and deoxygenation of sulfoxides
کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
15 صفحه اولSynthesis of structured filamentous zeolite materials via ZSM-5 coatings of glass fibrous supports
Structured filamentous zeolitic materials were synthesized by ZSM-5 coatings deposited on the glass fibrous supports. A homogeneous coverage of the support filaments was obtained via the synthesis of MFI crystals in fluoride-containing media at neutral pH ∼7. These materials combine the open macrostructure of woven filamentous fabrics with well-defined microstructure of ZSM-5 crystals. The samp...
متن کاملSynthesis of new zeolite structures.
The search for new zeolites is of continuous interest in the field of zeolite science because of their widespread application in catalysis and adsorption-separation. To this end, considerable efforts have been devoted to the preparation of new zeolites with novel porous architectures and compositions. Taking account of the key factors governing the formation of zeolites (e.g., guest species, fr...
متن کاملSynthesis of novel perfluoroalkylglucosides on zeolite and non-zeolite catalysts.
Perfluoroalkylglucosides comprise a very important class of fluorine-containing surfactants. These compounds can be synthesized by using the Fisher reaction, starting directly from glucose and the required perfluoroalcohols. We wish to report on the use of zeolite catalysts of different structure and composition for the synthesis of perfluoroalkylglucosides when using glucose and 1-octafluorope...
متن کاملDirect synthesis of hierarchical zeolite from a natural layered material.
Hierarchical SAPO-34 zeolite with high crystallinity and excellent hydrothermal stability was directly synthesized in the nanoscale confined environment provided by the natural layered material kaolin.
