چکیده
Crystallization of tri-O-[p-halobenzoyl]-myo-inositol 1,3,5-orthoformates from ethyl acetate-petroleum ether solution produced concomitant dimorphs that have different halogen bonding contacts; the kinetic form with C-Br...O-C contacts upon heating to 185 degrees C, converts completely to the thermodynamic form with C-Br...O=C contacts via crystal-to-crystal first order phase transition.

Adsorption of Crystal Violet Dye from Aqueous Solutions onto Low-Cost Untreated and NaOH Treated Almond Shell
In the present study, comparative batch adsorption of basic dye namely Crystal Violet (CV) using the almond shell as an adsorbent in untreated form and activated with sodium hydroxide was carried out in search of optimum adsorption conditions. The operation parameters investigated was contact time (10 to 80 min), initial dye concentrations (40-240 mg/L), temperature, (20-5...
متن کاملRegioselective Opening of myo-Inositol Orthoesters: Mechanism and Synthetic Utility
Acid hydrolysis of myo-inositol 1,3,5-orthoesters, apart from orthoformates, exclusively affords the corresponding 2-O-acyl myo-inositol products via a 1,2-bridged five-membered ring dioxolanylium ion intermediate observed by NMR spectroscopy. These C-2-substituted inositol derivatives provide valuable precursors for rapid and highly efficient routes to 2-O-acyl inositol 1,3,4,5,6-pentakisphosp...

Abstract: Two new transition metal complexes, containing the acidic ligand 5-chlorosalicylic acid (H2L5), and 1,10-phenanthroline（phen） and 1,3-Di(4-pyridyl)propane (bpp) as secondary ligands are reported. They are formulated as {[Pb(HL5)2(phen)(H2O)]·H2O}n(1), [Zn2(HL5)4(bpp)2]n(2). All the complexes are characterized by single-crystal X-ray diffractions. Compoud 1 crystallizes in the triclini...

A quantum chemical investigation was carried out to study the properties of intermolecular F•••F, Br•••Br and Br•••O interactions in crystalline 1-bromo-2,3,5,6-tetrafluoro-nitrobenzene (BFNB). This system was selected to mimic the halogen-halogen as well as halogen bonding interactions found within crystal structures as well as within biological systems. We found that fluorine atoms have weak ...
متن کاملApplication of Magnetic-modified Fe3O Nanoparticles for Removal of Crystal Violet from Aqueous Solution: Kinetic, Equilibrium and Thermodynamic Studies
The prepared magnetic-modified Fe3 O4 nanoparticles (Fe3 O4 -TAN) were used as adsorbent for removal of crystal violet (CV) from water solution. The effects of pH, contact time, dye concentration and temperature on adsorption were determined. The experimental data were analyzed using the Langmuir adsorption model. The data fitted well to the model with maximum adsorption capacities 84.0 mg/gund...
