Sui, Meng published the artcileStudy on the mechanism of auto-oxidation of Jatropha biodiesel and the oxidative cleavage of C-C bond, Recommanded Product: Methyl decanoate, the main research area is biodiesel methyl linoleate hexanal oxidation Jatropha.
Jatropha biodiesel was obtained according to the continuous preparation process which included vapor esterification – transesterification – methanol steam distillation Accelerated oxidation of small Jatropha biodiesel was obtained by the Rancimat method. GC-MS and liquid phase micro-extraction were used to study and analyze the components in the oxidation process of Jatropha curcas biodiesel. The electronic effects of the related reactants and products were calculated by d. functional theory, followed by the deduction of the related chem. reaction paths. Exptl. investigation shows that Me linoleate is the main factor affecting the oxidation stability of the Jatropha biodiesel. The main volatile products at the initial stages of the oxidation of Me linoleate are hexanal, Me octanoate, styrene, and 2-heptenal. The cis/trans-3-octyl-oxiranyl octanoic acid Me ester (18.03% yield) is produced by the reaction of peroxy acid and Me oleate during the oxidation of Me oleate. The hydrogen extraction reaction is difficult to occur, and the oxidation reaction energy barrier is relatively high due to the relatively large bond energy of the C-H bond in the Me stearate mol. In this manuscript, the auto-oxidation mechanism of the biodiesel fatty acid Me esters at the initial stage of oxidation, the path of oxidative cleavage of the C-C bond of Jatropha biodiesel and the formation process of ethylene oxide structure are obtained through DFT calculation and anal. of the oxidation products.
