Abstract
This research study involves transesterification of mango seed kernel butter using methanol as solvent and Tetra Hydro Furan (THF) was used as co-solvent in converting biodiesel. High density and higher acid value in biodiesel cause less thermal efficiency in the engine. The percentage yield of biodiesel has been studied under various parameters such as the molar ratio of methanol: oil, type of alkali catalyst and catalyst concentration (%). As the significant results, the highest biodiesel yield% was attained using the molar ratio of methanol to mango seed oil at 7:1 using sodium hydroxide as alkali catalyst with the catalyst concentration of 1.0% and THF co-solvent. The maximum %yield obtained was 90.79%. The produced biodiesel was characterized by Gas Chromatography-Mass Spectrometry (GC-MS). The properties of biodiesel were analysed, such as freezing point, acid value, saponification value, density, and specific gravity with the respective values of 15, 0.85 mg/g, 70.13 mg/g, 788 kg/m3, and 0.788, 11 fatty acid methyl esters were found in different concentrations. Analysis of Variance (ANOVA) has been used as a statistical method for optimization to validate the results obtained. The biodiesel results met the ASTM-D6751 and EN14214 standards for use as a working fluid.
