Production of epoxidized palm oil derived oleic acid by using peracid mechanism / Pascal Perrin Anaj Jites and Mohammad Jumain Jalil

Epoxidation study has changed a lot in world consumption of raw material where the costeffective and eco-friendly product is much safer for consumer to used. This practice is very reliable to achieve the increasing demand in every consumer especially in vegetable oil. Epoxidation of oleic acid was carried out by in situ performic acid to produce epoxidized oleic acid with enzymatic reaction. Since epoxide ring is highly reactive where the degradation of the oxirane was tested by using hydrogen peroxide, formic acid and water. The degradation of the epoxide is mainly focus on the rate of reaction between molar ratio of chemical. Thus, the study on degradation of the epoxide is lacking. With the initial concentration of formic acid at 1.4714 mol/L, while hydrogen peroxide and oleic acid are 2.948 mol/L respectively. Then, the kinetic rate, k parameters obtained k11= 6.6642, k12= 11.0185, k21= 0.1047, for epoxidation palm oleic acid, and k31= 0.0538 in epoxidation process. The minimum error of the simulation is 0.0967. Besides, optimizing molar ration between the chemical was done through epoxidation and the optimum condition obtained are H2O2/OA unsaturation molar ratio and FA/OA molar ratio with the temperature of 35°C (level 1), agitation speed at 100 rpm (level 1) specifically.
