Oxygen halides

Applications Basic methods for the determination of halogens in polymers are fusion with sodium carbonate (followed by determination of the sodium halide), oxygen flask combustion and XRF. Crompton [21] has reported fusion with sodium bicarbonate for the determination of traces of chlorine in PE (down to 5 ppm), fusion with sodium bisulfate for the analysis of titanium, iron and aluminium in low-pressure polyolefins (at 1 ppm level), and fusion with sodium peroxide for the complexometric determination using EDTA of traces of bromine in PS (down to 100ppm). Determination of halogens in plastics by ICP-MS can be achieved using a carbonate fusion procedure, but this will result in poor recoveries for a number of elements [88]. A sodium peroxide fusion-titration procedure is capable of determining total sulfur in polymers in amounts down to 500 ppm with an accuracy of 5% [89].

The structural information at an atomic level is essential for understanding the various properties of supercooled and glassy solutions. X-ray and neutron diffraction enables us to obtain direct structure information (bond distance and coordination number) of ionic solutions in terms of the radial distribution function. In the case of aqueous lithium halide solutions. X-ray diffraction data are dominated by halide-oxygen, halide-oxygen, and oxygen-oxygen interactions. On the contrary, neutron isotopic substitution...

There are, of course, numerous examples of elimination reactions involving the loss of water, hydrogen halides, oxygen, nitrogen, and other small molecules with the formation of a double bond. Both direct and indirect methods are employed, including processes with soluble precursor polymers. It is interesting to note that polymerization of phenyl vinyl sulfoxide and subsequent elimination of benzenesulfonic acid lead to the formation of PA. 

If L is a TT-acceptor ligand, irradiation of M(CO)jL can produce substitution at all three sites, but now loss of carbonyl is more important than L loss (see Table 1 for examples). If L is sufficiently like CO, complete substitution can be obtained with longer irradiation times . With non-rr-acceptor ligands, substitution is limited to one carbonyl (halides, oxygen donors) or to two or three carbonyls (amines), because increasing substitution results in a buildup of electron density on the metal. As expected, the photoreactivity patterns " of cis-M(CO) Lj parallel those of MfCOjL.
