Vapor-phase reactions chain branching

Free Radical Trap Theories. Combustion vapor-phase reactions have been studied using premixed gas flames such as methane. Considerable information concerning the mechanism of flame propagation has resulted from this work 40, 49, 50). Basically the process occurs predominantly by branching chain reactions among free radicals. The major chain branching reactions are... [Pg.544]

Thus the inhibitive effect results from the removal of active oxygen atoms (O ) from the vapor phase. Additional inhibition can result from removal of OH radicals in the chain-branching reactions ... [Pg.545]

Vapor-phase polycondensation has the distinct advantage of not having to use solvent and it makes possible the elimination of by-product HCl in the gas phase. However, the resulting polymers are usually highly branched due to the high reaction temperature required to maintain chain mobility. In addition, the stoichiometric balance of reagents is much more difficult to maintain than in the case of a condensed phase reaction. [Pg.1000]
