The title compound, C(12)H(8)N(2)O(5), was obtained by the reaction of 1-chloro-2,4-dinitro-benzene and phenol in the presence of potassium carbonate. The nitro-substituted benzene ring lies on a mirror plane, with one NO(2) group in the same plane and the other disordered across this plane. The phenoxy-benzene unit is placed perpendicular to this mirror, resulting in an exact orthogonal relati...

The title compound, C(19)H(19)NO(10), was obtained from the reaction of α-d-1-bromo-2,3,4-tri-O-acetylxylose with N-hy-droxy-phthalimide in the presence of potassium carbonate. The asymmetric unit contains two independent mol-ecules, in which the O-CH-O-N torsion angles are 73.0 (4) and 65.0 (4)°. The hexa-pyranosyl rings adopt chair conformations and the substituent groups are in equatorial po...

The linear attenuation coefficient (LAC) and mass (MAC) are most important while studying of radiation, radio-isotopes in dosimentry irradiation materials. In the present work to calculate values different salts samples by using Gamma-ray spectrometry with Photo-Multiplier Tube (PMT) Multi-Channel Analyzer (MCA). 0.123, 0.511, 0.662, 1.17, 1.28 1.33MeV gamma energy rays used for experiment inte...

The title compound, C(15)H(12)F(2)O(3), has been obtained by the reaction of 2,4-dihy-droxy-lacetonephenone, potassium carbonate and 3,5-difluoro-benzyl bromide. The hy-droxy group is involved in an intra-molecular O-H⋯O hydrogen bond in each of the two independent mol-ecules in the asymmetric unit. The dihedral angle between the aromatic rings is 0.5 (2)° in one molecule and 1.9 (2)° in the ot...

Thioalkalivibrio sp. K90mix is an obligately chemolithoautotrophic, natronophilic sulfur-oxidizing bacterium (SOxB) belonging to the family Ectothiorhodospiraceae within the Gammaproteobacteria. The strain was isolated from a mixture of sediment samples obtained from different soda lakes located in the Kulunda Steppe (Altai, Russia) based on its extreme potassium carbonate tolerance as an enric...

With synthetic wastewater, lab-scale batch experiments and column experiments were carried out to investigate the adsorption characteristics of ammonium ion by zeolite 13X which is a hydrothermally synthetic byproduct accompanied with preparation of potassium carbonate from insoluble potash ores. The Langmuir and Freundlich models were applied to describe the equilibrium isotherms for ammonium ...

The crystal structure of (Li0.5K0.5)2C03 was determined by neutron powder diffraction. A final weighted R-factor of 4.54% was obtained for the refinement of 2373 reflections by the Rietveld method from a sample synthesized using 7Li2CO3 and K2CO3 (99.9% pure). Slight distortion of the CO$units in the monoclinic cell was observed; the O( 1)-C-0(2) angle and CO(3) length are larger than those for...
