Abstract :The low-cost feedstocks such as sesame insert ignore into journalissuearticles values(sesamum indicum); and jatropha insert ignore into journalissuearticles values(jatropha curcas); seed oils were utilized to optimize the yield of alkyd resins. The experimentally selected input factors ranges in the molar ratios of oil:glycerol insert ignore into journalissuearticles values(0.3 – 1);, phythalic anhydride: glycerol insert ignore into journalissuearticles values(1 – 3);, and catalyst insert ignore into journalissuearticles values(0.5–1.5 wt. %); for optimization were established using the response surface methodology insert ignore into journalissuearticles values(RSM); of Box Behken model to improve the alkyd resin yield factors. The optimization solution utilizing CaCO3 catalysts, and a combination of other process factors evaluated, as well as the corresponding desirability functions, was found using analysis of variance insert ignore into journalissuearticles values(ANOVA); results for refined sesame alkyd resin insert ignore into journalissuearticles values(RSAR); and refined jatropha alkyd resin insert ignore into journalissuearticles values(RJAR);. The RSAR optimization using a CaCO3 concentration of 1.5 wt. % at a molar ratios of oil:glycerol insert ignore into journalissuearticles values(1.0:1.0); and phythalic anhydride:glycerol insert ignore into journalissuearticles values(3.0:1.0);, while the RJAR at a similar catalyst concentration of 1.5 wt. %, molar ratio of oil:glycerol insert ignore into journalissuearticles values(1.0:1.0);, and phythalic anhydride:glycrol insert ignore into journalissuearticles values(2.8:1.0); were observed for the alkyd resin optimization for the two processes. At these reaction conditions, the predicted and experimental biodiesel yield were 48.26 % and 47.29 % for RSAR and 62.07 % and 61.61 % for RJAR, respectively which shows less than 0.5% variations in both cases.
