This work represents a first contribution on the synthesis of nanoarchitectured materials based on layered titanosilicates of the JDF-L1 type growth on sepiolite fibrous clay. It has been observed that the main structural and textural characteristics of the resulting materials depend on the expe...

A synthesized zeolite/sepiolite nanoheterostructure (Zeo-Sep) and a modified organo-sepiolite (O-Sep) have been employed as clay-based adsorbents to study the adsorption mechanism of ibuprofen (IBP) from aqueous solution. New equilibrium data of IBP adsorption were determined at 20–60 °C, whic...

Un-exchanged and Zn or Cu ion exchanged samples of a newly discovered sepiolite clay from Greece were combined with nanophase anatase titania for the synthesis of sepiolite based nanocomposites and tested for oxidation of NOx gases. The Zn or Cu ion exchanged clay was modified by replacing the e...

As one of nature clay minerals, sepiolite was used in various fields, such as photocatalytic, refractory, and dye adsorption, but rare in superhydrophobic application. In this study, sepiolite was modified by polysiloxane ([email protected]) and its microstructure, chemical composition, and hydr...

Natural sepiolite mineral has been commonly used in the industry because of its unique structure and physical properties. In this paper, we fabricated sepiolite-based battery separators by simple and inexpensive electrospinning technology. The as-prepared sepiolite-based separators show high the...

Mononuclear organoeuropium sandwich complexes were synthesized from ligands of 1,3,5,7-cyclooctatetraene (COT) and 1,4- and 1,6-bis(trimethylsilyl)-cyclooctatetraenes (COT″) in a liquid ammonia of europium (Eu) and lithium (Li). Elemental analyses revealed the chemical compositions as [(DME)Li]...

A new synthesis of leukotriene B3 methyl ester is reported, starting from bis(trimethylsilyl) unsaturated derivatives as building blocks for the triene moiety of the leukotriene. The two stereogenic centers have been generated by enantioselective chemical reduction of two acetylenic ketones with...

In order to develop new and low cost anticoagulants as potential heparin alternatives, sulfation of a pectin-like polysaccharide from Opuntia ficus indica cladodes using SO3-DMF complex was performed with a significant sulfate content (7%). FTIR and NMR assays indicated that the sulfation reacti...

A convenient method for the synthesis of N,N-bis(trimethylsilyl)alkylamines has been reported. N-(Trimethylsilyl)diethylamine incorporated with a stoichiometric amount of methyl iodide was effective to convert primary amines, especially aromatic amines, and their monotrimethylsilyl derivatives i...

Treatment of the pyridinium salts of glycosaminoglycans and galactan sulfates with N,O-bis(trimethylsilyl)acetamide (BTSA) in pyridine for 2 h at 60 °C caused specific 6-O-desulfation without depolymerisation or other chemical changes.

1,1-Bis(trimethylsilyl)-2-phenylethylene (1), which has been synthesized from the Peterson reaction between (Me3Si)3CLi and benzaldehyde, reacts with various acyl chlorides (RCOCl, R = Me, Et, iso-Pr, n-Bu, iso-Bu, iso-C5H11, PhCH2, PhCH2CH2) in the presence of AlCl3 to give α-silyl-α,β-unsat...

Flusilazole is an organosilane fungicide used for treatments in agriculture and horticulture for control of diseases. The reaction kinetics and mechanism of flusilazole with sulfate and hydroxyl radicals were studied. The rate constant of the radicals with the fungicide were determined by laser ...

Original N-[bis(trimethylsilyl)methyl]-1,2- and 1,3-diamines of type I were prepared either from bis-imination reaction of 1,2-dicarbonyl compounds with bis(trimethylsilyl)methylamine, BSMA (1) followed by reduction or from cyanoethylation of BSMA followed by reduction of the nitrile group. By v...

Bis(trimethylsilyl) sulfate-silica has been shown to be an efficient reagent system for promoting thioacetalisation of carbonyl compounds at room temperature.

Dipole–dipole and/or hydrogen-bonding interactions between the pendant functional groups within maleated high-density polyethylene (PE-g-MAn) establish a physical polymer network, whose formation kinetics and shear-sensitivity are revealed by dynamic oscillatory testing. The pronounced time and...

Publisher SummaryThis chapter brings together information on the reactions of sucrose and illustrates some of the physical methods that have contributed to the characterization of sucrose derivatives. In addition, some of the potential commercial applications of compounds derived from sucrose ha...

Sucrose 6′-phosphate, the monophosphate of sucrose which is an intermediate in the biosynthesis of sucrose, has been synthesised by an unambiguous route. The known sucrose 2,3,6,3′,4′-penta-acetate (3) was converted into 6′-O-tritylsucrose (5) which, on per-O-acetylation and detritylation, a...

Enhancing the flavor of fruits plays a fundamental role in improving fruit quality, and volatile compositions as well as acid and sugar accumulation are significant factors that have an impact on the acceptability of sensory responses by human beings. Vacuoles in plants not only function as cell...

The distribution of substituents in O-carboxymethyl and O-cyanoethyl ethers of inulin was studied using 13C NMR spectroscopy and HPLC analysis. For both types of inulin derivatives, the distribution of substituents can be described by the statistical model of Spurlin, showing that the substituen...

The compound 2,3;22,23-dioxidosqualene has been found to accumulate in yeast grown in the presence of 10−4m 3β-(β-dimethylaminoethoxy)-androst-5-en-17-one. Subsequent removal of the latter compound permits the formation of 24,25-oxidolanosterol and more polar unidentified compounds.
