Abstract
ABSTRACTResponse Surface Methodology (RSM) was used to evaluate the effects of synthetic variables such as reaction time (6–12 hr), temperature (130–150°C), and substrate molar ratio of fatty acid methyl esters (FAME) of peanut oil to sucrose (10:1 to 14:1) on the % molar conversion to sucrose polyester, utilizing 10g of free sucrose as the reactant. Optimization of the synthetic reaction was performed by canonical analysis to derive the stationary point. Based on contour plots and canonical analysis, optimum conditions were: reaction time 11.5 hr, synthetic temperature 144°C, and substrate molar ratio 11.4:1. Predicted molar conversion was 43.39% (10g sucrose synthesized 29.4g sucrose polyester) at the optimum point. Experimental data indicated up to 48.4% yield based on theoretical % molar conversion.
