The neutralization of the model oil was carried out by mixing 10 g of dodecane with a set amount of IL in a round-bottom flask with a hot plate, reflux condenser, and magnetic stirrer. The stirring rate was kept at 500 rpm, and the reaction time was 1 h. Several temperature settings were used for the reaction to optimize the process temperature.
