Aluminum Magnesium Potassium Ammonium Sodium Lithium Producer perchlorate perchlorate perchlorate perchlorate perchlorate perchlorate

Commercial interest in perchlorates began in the late 1890s/early 1900s in Europe and the United States as a direct result of the pioneering efforts in rockets and their propulsion systems (Mendiratta et al. 1996). The production of ammonium perchlorate, the largest component of solid rocket propellants, far outpaced that of the other perchlorates listed in Table 4-1. Their commercial manufactu...

Determination of Perchlorate Ion With Tetraphenylarsonium Chloride

A detailed study of precipitation reaction of perchlorate ion with tetraphenylarsonium chloride is reported. Optimum conditions for quantitative precipitation of perchlorate ion were determined. A gravimetric and a spectrophotometric method for perchlorate ion are proposed. The spectrophotometric method is based upon dissolution of ( C.H.),AsClO. in acetonitrile and subsequent measurement of ab...

Charge Density

Low-temperature single-crystal neutron and X-ray diffraction data were collected for bullvalene (Figure 1). X —N Fourier and multipole static deformation electron density maps were calculated and compared. Atomic mean-square-displacement parameters were analysed in the framework of the rigid-body motion model and the residual amplitudes (UOBS — t/TLS) were graphically interpreted. The prelimina...

charge density.

We study the Euclidean two-point correlation function Gq(x) of the topological charge density in QCD. A general statement based on reflection positivity tells us that Gq(x) < 0 for x 6= 0. On the other hand the topological susceptibility χq = ∫ dxGq(x) is a positive quantity. This indicates that Gq(x) developes a positive contact term at x = 0, that contributes to the determination of the physi...

Determination of Trimethoprim Based on Charge-Transfer Complexes Formation

A spectrophotometric study concerning the interaction between Trimethoprim (TMP) ,Sulfamethoxazole (SFMx), as n-donor and 2,3-dichloro-5,6- dicyano-P-benzoquinine (DDQ) and chloranilic acid (CA) as π-acceptor were been performed at 25°C. The results of interaction of CA and DDQwith TMP indicate the formation of a 1:1, 1:2, charge transfer complexes through non equilibrium reactions. In the case...
