Abstract
A study has been made of the kinetic relationships governing the oxida tion of paraffinic hydrocarbon dodecane (RH) (140 degrees C) with addi tions of cationic surface-active substance (SAS) cetyltrimethylammoniu m bromide (CTAB) and anionic SASs sodium dodecylsulphate (DDS) and sod ium bis-(2-ethylhexyl)sulphosuccinate (AOT). In the presence of DDS an d CTAB (2.0 x 10(2) mole) there is a reduction in the oxidation rate a nd in the maximum hydroperoxide concentration. It has been established that additions of DDS and CTAB increase the decomposition rate of ROO H without the formation of free radicals. AOT additions have virtually no effect on the process. Intensification of the inhibiting action of ionol in the presence of DDS was found.
