Oxides and Oxyanions

The kinetics of the decay of CIO, prepared by the reaction of Cl with OCIO or with O3, have been followed by molecular beam mass spectrometry at 298 The major reaction gives Cl + ClOO and the minor reaction Cl + OCIO. The heats of formation of CIO, OCIO, and ClOO were estimated the latter two compounds are unimportant under stratospheric conditions because they will probably be photolysed. 

8—11 were found to be well represented by the equations. (12)—(14).The crystal structure of NaC102,3H20 has been determined by X-ray methods the

The reactions of chlorine perchlorate, CI2O4, with several fluoroalkyl halides have been examined by Schack et aO Under carefully controlled conditions, high yields of the novel perfluoroalkyl perchlorates R(OC103 (Rf = CF3, C2F5,

It has been suggested127 that oxides of chlorine, C10x, constitute an important sink for stratospheric ozone. The proposed photochemical scheme predicts that CIO is the dominant chlorine-containing constituent of the lower and middle stratosphere. The efficiency of 03-destruction of the C10x catalytic cycle appears to be greater than that of the NOx cycle.

The reduction of C102 in DMSO is complex it can be summarized by the equation  

According to Jander and co-workers140 the reactions of C1207 with NH3 or RNH2 (R = Me, Bun, Bu, or cyclohexyl) produce NFLt[NHC103] and RNHC103, respectively. The acidic hydrogens on N could be replaced with 

The role of C104 as a ligand in solution has been reviewed by Johansson.144 Perchlorate-ion-selective electrodes prepared using liquid ion-exchangers in PVC are said145 to exhibit approximately the same characteristics as the commercially available electrode the selectivity of the new electrode was claimed to be superior. The ion-exchanger was mixed with PVC dissolved in THF and the mixture dried as a membrane disc or used to coat a Pt electrode the useful life ranged from 2 weeks, for a wire electrode, up to a month.

Qualitative methods for the identification are given in Table 15. Quantitative methods are well documented. Sulfur compounds are readily studied by vibrational spectroscopy, both IR and Raman. The oxides and oxyanions have characteristic spectra in the IR while the sulfanes and cyc/o-sulfur compounds give strong Raman spectra as a result of their high polarizability. The only potentially useful NMR nucleus is S, which is quadrupolar and low in abundance (Table 2). In general, measurements of NMR... 

The Earth s sulfur cycle (Figure 22) transfers enormous amounts of this biologically important element through various reservoirs each year. Sulfur has a wide range of oxidation states and shows the ability to form a large number of oxides and oxyanions, many of which are found in the environment. It also has the potential to form polymeric species with a significant number of... 

However, the redox reactions of nitrogen oxides and oxyanions are generally slow. 

In a very recent paper various oxides and oxyanions of tellurium were reinvestigated with a source of electrodeposited on to platinum [45].
