Si-H containing functional initiators have been obtained by reduction with LAH of the corresponding Si-Cl containing compounds. Conditions have been developed under which the benzylic chloride remains unchanged while the Si-Cl bond is converted to Si-H (for experimental details see Sect. H.C.). The initiators obtained are shown in Table 1.

With aromatic compounds conditions can be found so that ring oxidation predominates and phenolic compounds are formed. Benzene is oxidized quantitatively to phenol. Toluene is oxidized to o-cresol, m-xy-lene to l,3-xylen-4-ol, and naphthalene to f-naphthol. The addition of certain additional catalyst, such as molybdenum oxide, promoted coupling reactions and biphenyl was formed from benzene, bi- or poly-tolyl hydrocarbons from toluene, di- and polyxylyls from wi-xylene, and a...

EPA currently uses the heat of combustion to rank the incinerability of hazardous compounds, although kinetics, not thermodynamics, govern incinerator performance. More important, because of interactions between species, rates of reaction of hazardous compounds in a mixture can be considerably different from those observed under single-compound conditions. Moreover, the hydrocarbon fuels used to cofire the incinerator can interact with the hazardous substances themselves.
