Sol–Gel Synthesis and Characterization of Microporous Silica Membranes
It has been reported in the literature that the composition Unsupported silica membranes were prepared by acid-catalyzed of the synthesis solution influences the structure of the spehydrolysis and condensation of tetraethylorthosilicate. The possicies in the sol (3) and, hence, the final structure of the bility of tailoring the pore size and porosity of microporous silica membrane. This possibi...
متن کاملsynthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
15 صفحه اولMicroporous Silica Based Membranes for Desalination
This review provides a global overview of microporous silica based membranes for desalination via pervaporation with a focus on membrane synthesis and processing, transport mechanisms and current state of the art membrane performance. Most importantly, the recent development and novel concepts for improving the hydro-stability and separating performance of silica membranes for desalination are ...

series (11) will present the synthesis chemistry of silica sols Silica-based microporous membranes can be successfully proto make unsupported membranes with predictable pore size/ cessed by sol–gel techniques. However tailor making of such memporosity. This article aims to give a detailed account of small branes is still not possible because of the unavailability of systemangle X-ray scattering...
