Synthesis and Characterization of Functionalized Se-MCM-41 a New Drug Carrier Mesopore Composite
Various nanocomposite materials play a number of important roles in modern science and technology including pharmaceutical science. Among these materials, mesoporous materials cover a large number of applications in drug delivery system. The quantitative incorporation and high dispersion of selenium nanoparticles into MCM-41 have been made possible by the coordination between Se(IV) ion and ami...

در این تحقیق روشی جهت سنتز یک سری از کمپلکس های پلاتین (ii) حاوی لیگاند های دهنده ی فسفری شامل فسفیت و فسفین ارائه شده است. واکنش پیش ماده ی پلاتین (ii)،trans/cis- [ptcl2(sme2)2] ، با 2 اکی مولار از لیگاند p(oph)3در حلال بنزن کمپلکس1، cis-[ptcl2(p(oph)3)2] را تولید می نماید. جهت سنتز کمپلکس سایکلو متال فسفیتی، کمپلکس 1 با 1 اکی والان واکنشگر ptcl2 در حلال زایلن در شرایط رفلاکس زیر گاز آرگون م...
Synthesis Characterization and Catalytic Evaluation of Mesoporous Fe-MCM-41 and Si-MCM-41 Materials
Environmental concern associated with safe handling disposal of corrosive mineral acids such as HF have encouraged the development of safer and non waste producing alternative for application in catalysis. In this sense ,mesoporous materials attracted much attention of catalysis to transform big molecules into its useful products. In the present study we have synthesized, mesoporous Fe-MCM-41an...
متن کاملSynthesis and characterization of composite molecular sieves comprising zeolite Beta with MCM-41 structures
Zeolite Beta/MCM-41 composites have been prepared with various crystallinities of zeolite Beta through a twostep crystallization process involving the combination of low crystallinity zeolite Beta synthesis gel with cetyltrimethylammonium bromide surfactant solution. The composites are characterized by XRD, SEM, Si and Al MAS NMR, N2 adsorption, NH3-TPD and catalytic cracking. The experimental ...
متن کاملAsymmetric Synthesis of Modafinil and its Derivatives by using the Functionalized Silica-based Mesoporous MCM-41
Modafinil [2-[(diphenylmethyl)sulfinyl]acetamide] is used clinically in the treatment of narcolepsy and sleeping disorders. The synthesis of modafinil, begins with the reaction of benzhydrol and thioglycolic acid in trifluoroacetic acid to afford benzhydrylsulfinyl acetic acid. The reaction of acid with thionyl chloride in benzene followed by treatment with ammonium hydroxide gave acetamide...
