“…Pitman et al 5 observaram uma correlação quantitativa de proporção inversa entre o valor de pKa de imidas e a capacidade de cloração da respectiva N-cloroimida. Assim, fazendo-se um paralelo entre os valores de pKa da succinimida (9,62) e da sacarina (1,30) tem-se que as N-halossacarinas são agentes halogenantes mais potentes que as N-halossuccinimidas correspondentes 6 .…”

“…Desta forma, nas N-halossacarinas o halogênio está muito mais disponível como eletrófilo que em outras N-haloimidas. Além disso, as N-halossacarinas são mais estáveis, tanto na forma cristalina quanto em soluções 4 .Pitman et al 5 observaram uma correlação quantitativa de proporção inversa entre o valor de pKa de imidas e a capacidade de cloração da respectiva N-cloroimida.

“…Although chloroamines are poor oxidizing agents and not as effective in disinfection as are nonaminated chlorines, they may be somewhat less likely to act as chlorinating reagents for carbon. As Jolley has noted (132), chloramines are aminating agents, and usually require basic conditions to react with alcohols or phenols (133,134 (135)(136)(137)(138)(139) for the chlorination of amines and amides. The chlorine potential for N-chlorinated derivatives has been defined as: pKcs = -log Kcp (28) where Kcp is the equilibrium constant for the following type of equilibria: R2NC1 + H20 R2NH + HOCI (29) R3+NC1 + H20 = R3+NH + HOCI (30) The chlorine potential is the free energy difference between the reactants and products and values for various amines can be determined experimentally if the pKcp for one amine is known, because of the following equilibrium:…”
