Four vegetable oils are converted into polyoleate esters, with evaluation of their physico-chemical properties as synthetic lubricants. Castor oil, linseed oil, sunflower oil, and jatropha oil were converted into polyols via epoxidation and hydrolysis. Esterification of these polyols with excess oleic acid gave the polyoleate esters 1, 2, 3, and 4, respectively. The results of physico-chemical determinations show that these esters are promising as synthetic lubricants. Esterification of castor oil itself with oleic acid gave the ester 5, which showed poor thermal and oxidative stabilities. © 2013 Copyright Taylor and Francis Group, LLC.

Three vegetable oils (sunflower, linseed, and jatropha) were subjected to two successive base-catalyzed transesterifications. First, they were converted into the corresponding fatty acids methyl esters, and then later they were converted into pentaerythryl esters. The physico-chemical characteristics of the esters obtained were evaluated applying the international standard methods. They proved to be promising as synthetic lubricants, and they show very good thermal and oxidation stabilities. © 2013 Copyright Taylor and Francis Group, LLC.

In this investigation, four vegetable oils (castor, linseed, sunflower, and jatropha) were treated with maleic anhydride in the presence of benzoyl peroxide as a radical initiator. The suitability of the adducts obtained as synthetic lubricants was tested by determining their physico-chemical properties applying the international standard methods. The oily adducts obtained proved to be promising as synthetic lubricants, especially their good thermal and oxidative stabilities. © 2013 Taylor & Francis Group, LLC.
