Abstract EN
Estolides are vegetable-oil-based lubricants obtained from oleic acid or any source of hydroxy fatty acids.
In this work, the estolides synthesis from oleic acid and methyl ricinoleate (biodiesel from castor oil), using immobilized commercial lipases (Novozym 435, Lipozyme RM-IM, and Lipozyme TL-IM) in a solvent-free medium was investigated.
Acid value was used to monitor the reaction progress by determining the consumption of acid present in the medium.
Novozym 435 showed the best performance.
Water removal improved the conversion.
Novozym 435 was more active at atmospheric pressure.
Novozym 435 was reused four times with conversion reaching 15% after the fourth reaction at 80°C.
Estolides produced under the reaction conditions used in this work presented good properties, such as, low temperature properties as pour point (−24°C), viscosity (23.9 cSt at 40°C and 5.2 cSt at 100°C), and viscosity index (153).
