Thermal and oxidative stabilities of binary blends of esters from soybean oil and non-edible oils (Aleurites moluccanus, Terminalia catappa, and Scheelea phalerata)

摘要: Abstract Edible oils remain the principal feedstocks for biofuel production. Given potential impact of this use on food supply chain, extensive research has supported adoption inedible biodiesel generation, an approach that may help diversify oleochemical materials. This article reports investigation Scheelea phalerata, Terminalia catappa, and Aleurites moluccanus, three oilseeds found in Midwest Brazil. Oils from these species were employed to synthesize (methyl route) produce binary blends with soybean (S. phalerata : soybean, T. catappa A. moluccanus each at 10:90, 20:80, 30:70, 40:60, 50:50). Investigation thermal oxidative properties esters individual plant blended showed alternative are suitable as biodiesels. The chemical composition profile transesterification products revealed a predominance saturated compounds (62.5%) S. oil, while more balanced distribution between (40.5%) unsaturated (57.4%) was high content (90.0%) detected moluccanus. had favorable effect blends, reducing stability, decreasing crystallization points, increasing induction periods. Higher ratios promoted increase stability Use led increased decreased temperatures
