Layer aluminosilicates catalyze reactions in numerous ways. They stabilize high-energy intermediates. can store energy their lattice structures and release it the form of chemical energy. redox serve as photocatalytic devices. often exhibit high surface acidity. Organic that are catalyzed by agency days reviewed. The role clays prebiotic chemistry is also examined.

A new, efficient preparation has been devised for potassium ferrate(VI) (K(2)FeO(4)). The ability of this high-valent iron salt oxidizing organic substrates in nonaqueous media was studied. Using benzyl alcohol as a model, the catalytic activity wide range microporous adsorbents ascertained. Among numerous solid supports aluminosilicate type, K10 montmorillonite clay found to be best at achieving quantitative formation benzaldehyde, without any overoxidation benzoic acid. roles various...
Just like glass flasks, beakers, and distillation columns, chemical structures are an integral part of our profession. We easily identified as chemists by how we draw formulas. Nonetheless, the simplicity these formulas—whether mere sketches or glossies fit for publication—is misleading. They pose numerous questions on ways represent structures. The picture right shows one way portraying a camphor molecule.
Partial dehydration in acetone activates iron(III) or copper(II) nitrate. These activated nitrato complexes, with covalent metal-ligand bonds, are stabilized a convenient form by impregnation upon modified montmorillonite clay (K10). mild and inexpensive reagents offer versatile applications to organic synthesis. As sources of nitrosonium cations (NO+), they perform number useful functional group interconversions. They effect also the regioselective mononitration phenols. 1. Introduction 2....

Abstract Catalysts are obtained by exchange of the interstitial cations in K10 montmorillonite. They applied to Friedel‐Crafts alkylations with halides, alcohols, and olefins. quite effective even unactivated hydrocarbons. Isomer distribution depends little on catalyst used. Thermodynamic equilibration does not take place, reactions appear be kinetically controlled. Efficiency catalysts bears no apparent relation that corresponding Lewis acids under homogeneous conditions, it nature...

Abstract With the availability of Fourier transform spectrometers, 23 Na‐NMR spectroscopy has become an important tool. It affords direct insight into solvation and ion pairing phenomena, both in organic bio‐inorganic systems. Monitoring chemical shifts linewidths Na signals gives access to binding constants, reorientational correlation times microdynamics sodium coordination shell. The other cations can also be studied by spectroscopy, competition experiments.
