Application of Response Surface Methodology to optimize the process of saponification reaction from coconut oil in Ben Tre

Abstract

    Response Surface Methodology (RSM) is used to optimize the conditions of the saponification reaction (Concentration of alkaline solution (%), temperature (^oC) and reaction time (hour)). Level of foaming and durability of the emulsion (cleaning ability) from the product of the saponification reaction are two factors to evaluate the optimization process by RSM. After optimization, the alkaline solution concentration is 11%, the reaction was carried out for 3 hours at 85^oC for the highest level of foaming 0,8 and the highest durability of the emulsion was 24,92 minutes. This parameter was compared with the experiment and the results showed that there was no significant error (6,86%, 2,08%), this proves that the RSM model has good repeatability, has the ability to optimally correct and is important in optimizing the survey parameters.
