TL;DR: In this article, the acyclic diene metathesis of vegetable oils utilizing Grubbs' ruthenium catalyst (Cy3P)2Cl2Ru = CHPh has been developed.
Abstract: A new process for the acyclic diene metathesis of vegetable oils utilizing Grubbs’ ruthenium catalyst (Cy3P)2Cl2Ru = CHPh has been developed. The higher molecular weight oligomers obtained can be separated from the unreacted oil and the lower molecular weight alkene by-products easily. The reaction proceeds in the absence of solvent, with very low catalyst concentrations (0.1 mole %) under moderate temperatures and low pressures. This process does not require the stringent exclusion of water and oxygen that the previous method (Me4Sn plus WCl6) required. Low pressures appear to favor polymerization by removing the alkene by-products. The metathesis reaction has been shown to be effective for many unsaturated vegetable oils, although some cases require oil pretreatment with silica gel. This process is effective on a 2–200 g scale. Chromatographic separation and characterization of metathesized soybean oil indicate that the process involves intermolecular and intramolecular carbon-carbon double-bond formation.

TL;DR: The results confirm the correctness of Vander Wal’s theory on the distribution of fatty acids in the triglycerides of vegetable natural fats.
Abstract: Cocoabutter, Sumatra palm oil, lard, groundnut oil, soybean oil and cottonseed oil have been analyzed by separating the triglycerides according to their degree of unsaturation by means of thin-layer chromatography on silica impregnated with silver nitrate. Of each triglyceride fraction obtained in this way, the fatty acid composition—overall and at the 2-position—has been determined. Moreover, the triglyceride composition of the fractions of cocoabutter, Sumatra palm oil and lard has been determined by means of gasliquid chromatography. The results confirm the correctness of Vander Wal’s theory on the distribution of fatty acids in the triglycerides of vegetable natural fats.

TL;DR: In this paper, a simple and reliable differential scanning calorimetric (DSC) method was developed for monitoring the oxidation in heated oils, which was based on the cooling thermogram of oil samples at a scanning rate of 1°C/min from −30 to −85°C.

TL;DR: In this article, a base catalysts with high transesterification efficiency to be used for heterogeneous biodiesel production was explored. But the results showed that a maximum TG conversion of 99.9% catalyzed by 2.1% catalyst was obtained with methanol/oil molar ratio of 12:1.
