TLDR
The acid-catalyzed reaction of soybean oil with the homologous series of straight-chain alcohols: methyl, ethyl, n-propyl and n-hexyl in a pressurized system yielded completely transesterified products and 18-31% substituted alkyl ethers.Abstract:
The acid-catalyzed reaction of soybean oil with the homologous series of straight-chain alcohols: methyl, ethyl, n-propyl, n-butyl and n-hexyl in a pressurized system yielded completely transesterified products and 18-31% substituted alkyl ethers. Mass spectrometry of the hydrogenated methyl ester derivatives showed that the addition reaction occurred at one of three double bonds of the unsaturated fatty acids. The reaction with three secondary alcohols yielded only 0.1-2.5% substituted alkyl ethers.read more

Effect of structure on properties of polyols and polyurethanes based on different vegetable oils
TL;DR: In this paper, the authors synthesize polyurethane networks from 4,4-diphenylmethane di-isocyanate and polyols based on midoleic sunflower, canola, soybean, corn, and sunflower oils.

Alkoxylation of biodiesel and its impact on low-temperature properties
TL;DR: In this paper, an epoxidation of the unsaturated portion of biodiesel offers the potential benefit of reduced cloud point without compromising ignition quality or oxidation stability, and the results showed that the reduction in cloud point for methyl and ethyl biodiesel increased slightly, while a reduction of 1 K was achieved for butyl butyl.

Volatile by-products during heat polymerization of soybean oil
TL;DR: In this paper, by-products during heat polymerization of soybean oil at 330°C were analyzed using GC-MS and NMR, showing that about 90% of the byproducts were decanoic, palmitic, linoleic, oleic, and stearic acids.

TL;DR: In this article, an experimental study on the application of metal triflate salts for the trans- esterification of fatty esters (triolein, methyl oleate, methyl linoleate), fatty acid (oleic acid), as well as Jatropha curcas L. oil with methanol and higher alcohols was described.

Synthesis of secondary ethers derived from meadowfoam oil
Terry A. Isbell,Melissa S. Mund +1 more
TL;DR: The 5-ether fatty esters and the process for their formation have not been previously known and appear to be limited to structures where stabilized cations can be formed by nuclear magnetic resonance and gas chromatography-mass spectrometry as discussed by the authors.

Ion exchange resin catalyzed addition of alcohols to olefins
TL;DR: In this paper, an experimental study was carried out on addition of alcohols to tertiary olefins catalyzed by a macroporous sulfonic acid resin, and the ion exchange resin displays an activity higher than soluble anhydrous p -toluenesulfonic acid.

Boron trifluoride as catalyst to prepare methyl esters from oils containing unusual acyl groups
TL;DR: The procedure of Metcalfe et al. as discussed by the authors for the preparation of fatty acid methyl esters, using boron trifluoride as catalyst, is shown to be suitable for use with oils containing fatty acids of unusual structures, such as conjugated unsaturation, hydroxyl or epoxy groups, and cyclopropenes in addition to oils with only the common acids.
