A Response Surface Methodology to Optimize the Vield of Alkyd Resin from Jatropha (Jatropha Curcas) and Sesame (Sesamum İndicum) Seed Oils Using CaCO3 as Catalyst

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