- Abstract:
- ... Estolides are bio‐based oils synthesized from fatty acids or from the reaction of fatty acids with vegetable oils. Estolides have many advantages as lubricant base oils, including excellent biodegradability and cold flow properties. Promising applications for estolides include bio‐lubricant base oils and in cosmetics. In this review, the synthesis of estolides from fatty acids using four different ...

- Abstract:
- ... Using the universal calibration and the Mark‐Houwink equation (MHE) (ηj=KMjα), three batches of oleic estolide acids and their corresponding 2‐ethylhexyl esters were characterized using gel permeation chromatography (GPC). The MHE parameters in tetrahydrofuran (THF) at 40 °C were determined (for acids: α = 0.442 ± 0.003 and log₁₀K=2.505 ± 0.007, for esters: α =0.531 ± 0.006 and log₁₀K =2.794 ± 0.0 ...

- Abstract:
- ... A new series of pennycress (Thlaspi arvense L.) based free-acid estolides was synthesized by an acid-catalyzed condensation reaction, followed by an esterification reaction to produce the 2-ethylhexyl (2-EH) esters of the initial estolides. The physical properties of the estolides are highly affected by the length and unsaturation level of the capping fatty acid, the base fatty acid unit, and esto ...

- Abstract:
- ... Hydroxy fatty acids (HFAs) have found a number of uses in today's market, with uses ranging from industrial materials to pharmaceuticals. Castor oil, which is obtained from castor seeds, has served as a source of a versatile HFA; its principle component, ricinoleic acid, can be isolated from castor oil and has been modified extensively for a number of applications. Unfortunately, castor seeds also ...
