J. Kubo et T. Kubota, INHIBITION OF THE CHANGES IN DIELECTRIC-PROPERTIES CAUSED BY THE OXIDATION OF HYDROCARBONS, Industrial & engineering chemistry research, 36(6), 1997, pp. 2171-2176
The additive effects of multicomponent hydrogen-donating hydrocarbons
derived from petroleum (HHAP) on the changes in the dielectric propert
ies caused by the oxidation of hydrocarbons were tested compared with
conventional antioxidants, and the following results were obtained: (1
) The addition of HHAP to LDPE did not affect the dissipation factor,
in contrast to the changes caused by the conventional hindered phenoli
c and bisphenolic antioxidants. (2) During the oxidation of n-paraffin
wax at 160 degrees C in air, the changes in dissipation factor caused
by the oxidation were sufficiently inhibited by the addition of HHAP
(1 and 2 wt %). (3) The results of the chemical analyses, including IR
, acid value, and oxygen content, were well consistent with the dissip
ation factor. These outcomes are attributable to the high radical-scav
enging ability and the pure hydrocarbon constitution of HHAP, which ha
s no functional groups that contain heteroatoms.
