Synthesis of N-o-methylphenyl-N'-(sodium p-aminobenzene-sulfonate) thiourea and its chromogenic reaction with palladium(II).
A new chromogenic reagent, N-o-methylphenyl-N'-(sodium p-aminobenzenesulfonate)thiourea (MSAT), has been synthesized and characterized by elemental analysis, (1)H-NMR, FT-IR and UV-Vis spectra. Based on the absorption spectrum of the colored complex of MSAT with palladium(II), a novel spectrophotometric method for the determination of palladium has been developed. In a pH 4.0 - 5.5 HAc-NaAc buf...
متن کاملLITHIUM PERCHLORATE MEDIATED AMINATION REACTION OF ALDEHYDES: A NOVEL METHOD FOR SYNTHESIS OF N, N-DIALKYL-p-SILYLATED AMINES*
P-Silylated N,N-dialkyl amines (5) were easily synthesized in good to excellent yield from aldehydes (1), trimethylsilyldialkylamines (2), and trimethylsilylmethylmagnesium chloride (4) in the presence of 5 M lithium perchlorate solution in diethyl ether. The reaction Of (2) with aldehyde proceeded smoothly in the LiCI0 , to give the imimum salt (3). Addition of trimethylsilylmethylrnagnes...
متن کاملMeasurement of the Quasi-free P+n!p+n+ Reaction
The rst measurement of the quasi-free p+n!p+n+ reaction cross section has been made at the CELSIUS storage ring using a deuterium internal cluster jet target. The energy dependence of the cross section is extracted using a xed incident proton energy of T p = 1350 MeV and exploiting the Fermi momentum of the struck neutron. The data cover a range of centre-of-mass excess energies from 16 MeV to ...

The relevance of security as one of the major contributors to an effective operational infrastructure has been growing in importance over the past 3-5 years, and today it resides as one of the two top investment priorities for senior management (the other one being critical server virtualization). Effective management by organizations when dealing with targeted and multiple parallel attacks com...
