Degradation of the Oxirane Ring of Epoxidized Vegetable Oils in a Liquid-liquid-solid Heterogeneous Reaction System
(Elsevier Science Sa, 2007-12)
The main oxirane-ring opening reactions that occur during the manufacture of epoxidized vegetable oils using a strongly acidic, gel-type ionexchange resin (IER) (Amberlite IR-120, 8% crosslinking) were analyzed. By using ...
Degradation of the Oxirane Ring of Epoxidized Vegetable Oils with Hydrogen Peroxide Using an Ion Exchange Resin
(Elsevier Science, 2005-12)
The influence of different process variables (stirring, temperature, hydrogen peroxide concentration, particle diameter and amount of catalyst added) on the oxirane ring-opening reaction caused by hydrogen peroxide (H2O2) ...
Degradation of the Oxirane Ring of Epoxidized Vegetable Oils with Solvated Acetic Acid Using Cation-exchange Resins
(Wiley VCH Verlag, 2004-05)
Vegetable oil epoxides (oxiranes) are customarily manufactured using acetic acid (AA) as oxygen carrier and reactant source, in aqueous/organic media. Further attack of the oxirane ring by AA proceeds in this acid-catalyzed ...

Degradation of the Oxirane Ring of Epoxidized Vegetable Oils in Liquid-liquid Heterogeneous Reaction Systems
(Elsevier Science Sa, 2006-12)
The reaction regimes under which proceed some of the relevant and deletereous consecutive reactions that occur during the conventional epoxidation process of vegetable oils were analyzed in detail, considering – separately ...
