chlorinechlorinationchloroethylsilanesC-chlorosilanesIR spectra1H NMR spectraLiquid-phase chlorination of a number of chloro(chlorovinyl)methylsilanes was investigated. A number of novel C -chlorosilanes were characterized by IR and 1 H NMR spectra. Some regularities of these reactions were determined;...

It was therefore clear that spectroscopic and SAXS measurements alone failed to conclusively determine the specific molecular effects of the ionic liquids on protein structure. To investigate the effects of [OTf]−in greater detail, we turned to NMR spectroscopy.1H-15N heteronuclear single quantum co...
223 Monitoring the reaction with 13C NMR spectroscopy revealed that methanol was produced via disproportionation of formic acid rather than direct CO2 hydrogenation.223 The catalytic reactivity of the hydrogenation/disproportionation of formic acid to methanol was further enhanced by using an iridium ...
All-electron basis sets of quintuple-zeta quality were employed for the bridging ligands and triple-zeta basis functions for the remaining chlorine anions of the reference octa- hedra45. We further utilized two f polarization functions44 for each Ru ion of the central, reference unit and four d...
Nmr-spectroscopyProteinAdductWe report the application of high-performance liquid chromatography (HPLC) linked to inductively coupled plasma mass spectrometry (ICPMS) and orthogonal acceleration time-of-flight mass spectrometry (oa-TOFMS) for the identification of phase I and II urinary metabolites of ...
The utility model relates to a tube box and tube plate mechanism, in particular to a tube box and tube plate mechanism for a liquid chlorine carburetor. The tube box and tube plate mechanism for the liquid chlorine carburetor is used for the field of chemical industry. The tube box and tub...
The beetle elytron surface is composed of 83.64% of carbon and 9.90% of oxygen. This is consistent with a surface made of polysaccharide chains such as chitin and with the literature34,35. Chlorine, phosphorus, sodium and potassium are found in very small amounts. Calcium was also detected ...
composition in Example 2. The invention also includes a mixture in which at least two compositions in Examples were mixed. The thus prepared compound was identified by methods such as an NMR analysis. Characteristics of the compound, the composition and the device were measured by methods ...
19 F NMR of the product in chlorotrifluoromethane gave a small-triplet at -77.7 ppm (vs. CFCl3) and a large singlet at -88.7 ppm corresponding to the terminal and interior difluoromethylene of perfluoropoly(ethylene glycol), respectively. ##STR8## No definitive peak corresponding to a mo...
