Influence of diluent on radiolysis of amides in organic solution

The radiolytic behavior of N,N,N',N'-tetraoctyldiglycolamide, N,N'-dimethyl-N,N'-dioctyl-2-(3'-oxapentadecyl)malonamide, and N,N'-dioctylhexanamide in n-dodecane was investigated by irradiation with gamma-rays and electron pulses. The results showed n-dodecane has a sensitization effect on the radiolysis of these amides, owing mainly to a charge transfer from radical cations of n-dodecane to the amide molecules in the primary process observed in pulse radiolysis. This result was supported by the difference in the ionization potentials between n-dodecane and these amides. (C) 2006 Published by Elsevier Ltd.
