Influence of iron solubility and charged surface-active compounds on lipid oxidation in fatty acid ethyl esters containing association colloids

“…In addition, the presence of Tween 20 did not significantly influence lipid oxidation rates in W/O emulsions compared to the control (Yi et al, 2014). Similar results were found by Kasaikina that CTAB accelerated radical chain oxidation of ethyl benzene and cumene, and anionic surface-active compounds (SDS and AOT) either have no effect on the oxidation rate or decrease it (Denisov & Afanas'ev, 2005;Trunova, Kartasheva, Maksimova, Bogdanova, & Kasaikina, 2007;Trunova, Krugovov, Bogdanova, & Kasaikina, 2008). Our results are consistent with lipid oxidation results in W/O emulsions and radical chain oxidation of hydrocarbons.…”

“…However, Denisov and Trunova reported that CTAB exerts a catalytic effect on the process of radical chain oxidation of hydrocarbons (Denisov & Afanas'ev, 2005;Trunova et al, 2007Trunova et al, , 2008. Their kinetic study showed that the acceleration was caused by the ability of the bromide ion of CTAB to form free radicals and accelerate the decomposition of lipid hydroperoxides.…”

Catalysis of radical decomposition of hydroperoxides on the surface of modified montmorillonite

“…(2′) is equal to 61 kJ/mol. This value is close to the literature data on the activation energies of CHP decomposition into radicals in aqueous solutions in the presence of cetyltrimethylammonium chloride (68 kJ/mol) and bromide (79 kJ/mol) [7]. It also cor responds to the estimations made in [7], where the decomposition of CHP in chlorobenzene in the pres ence of a surfactant was shown to weakly depend on temperature.…”

“…These factors are known to be most important when studying processes involving reverse micelles and microemulsions formed in organic solvents [7].…”
