Poly (vinylpyrrolidone)-Grafted Silica as a Polymeric Cosolvent Catalyst for Organic Transformations in Organic and Aqueous Media
Poly (vinylpyrrolidone)-grafted silica as an organic-inorganic hybrid material was used as an effective heterogeneous polymeric cosolvent catalyst in organic reactions. This modified silica catalyzed nucleophilic displacement of alkyl halides for easy preparation of alkyl thiocyanates, alkyl cyanides, alkyl azides and alkyl aryl ethers. Furthermore, the catalyst was applied for the conversion o...

متن کاملComputational Model of Reaction Mechanism of Alkyl Peroxy Radicals with Organic Compounds in the Presence and Absence of Oxygen
On the basis of experimental data a kinetic model for the heterogeneous interaction between alkylperoxyradicals and organic compounds in Langmuir- Hinshelwood approach at room temperature has been offered.The effect of oxygen on the kinetics of process in the presence, [O2]o = 1 x 1011 – 1.6 x 1012 molecules.cm-2, and absence of oxygen has been analyzed. Over time the chain degenerate branching...
متن کاملcritical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
