Microemulsion fuels have involved oil, alcohol, surfactant, and cosurfactant/amphiphilic molecule. A system of chemical reactions takes place between phase boundaries. Palm oil as vegetable oil has been assessed as a renewable resource. So, before applying microemulsions, an immiscible mixture (palm oil and ethanol) needs to be evaluated for the chemical activity, such as suspected defects. This study aimed: to determine the presence of defect products that occurred at the phase boundary of the palm oil:ethanol mixture, and to determine the influence of amphiphilic chitosan/Zeolite LTA toward the palm oil:ethanol mixture. This research was carried out through: (1) preparation of zeolite LTA, (2) synthesis of amphiphilic chitosan/Zeolite LTA, (3) application of phase boundary reactions in an immiscible mixture of palm oil:ethanol. The results have shown that the synthesis of amphiphilic chitosan/Zeolite LTA was successful as confirmed by XRD, FTIR, and SEM. Furthermore, the application of the reaction between oil:ethanol has shown that there were defect products as a result of chemical mixtures and interactions that occurred. This study has proven that the defect activity can occur in the liquid phase. © 2022 Elsevier B.V.
