Synthesis of Novel Perfluoroalkylglucosides on Zeolite and Non-Zeolite Catalysts [PDF]
Molecules, 2015 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 ...

Tunable hybrid zeolites prepared by partial interconversion
Nature Communications, 2023 Hybrid zeolites, which are materials made of building units from various zeolites, have been prepared by partial interzeolite transformation. The relative proportion of the various zeolites can be conveniently tuned to optimize their catalytic ...

Synthesis of ‘unfeasible’ zeolites [PDF]
Nature Chemistry, 2015 Zeolites are porous aluminosilicate materials that have found applications in many different technologies. However, although simulations suggest that there are millions of possible zeolite topologies, only a little over 200 zeolite frameworks of all compositions are currently known, of which about 50 are pure silica materials.

Benzene Alkylation by Ethanol over Catalysts on the Base of Modified Natural Zeolites
Eurasian Chemico-Technological Journal, 2012 Alkylation of aromatic compounds with ethanol was researched on modified natural zeolites of Kazakhstan deposits. These natural zeolites were identified as Clinoptilolite-Heulandite type.

Silicon aluminium ordering in the framework of zeolites [PDF]
Bulletin of the Geological Society of Finland, 1985 The (Si, Al) ordering scheme in the framework of zeolites is reviewed, and four classes are recognized: 1 ‒ zeolites with Si:Al = 1 : 1 and a simple order given by the alternation of Si and Al; 2 ‒ zeolites with Si> Al and an ordered distribution; 3 ...

Molecular dynamics as a tool to study heterogeneity in zeolites - Effect of Na cations on diffusion of CO and N in Na-ZSM-5 [PDF]
, 2014 Zeolites typically contain extra-framework cations to charge-compensate for trivalent Al atom substitutions in the SiO framework. These cations, such as Na, directly interact with quadrupolar guest molecules, such as CO and N, which move through their ...
