Biolubricant Production from Stearic Acid and Residual Secondary Alcohols: System and Reaction Design for Lipase-Catalyzed Batch and Continuous Processes

Six lipases were immobilized on a styrene–divinylbenzene support and evaluated on the batch esterification reaction of stearic acid with fusel oil. After a screening design, the two most appropriate lipases were assayed on a packed-bed system, achieving high conversion rates (90–93%) and productivit...

Description
Summary:Six lipases were immobilized on a styrene–divinylbenzene support and evaluated on the batch esterification reaction of stearic acid with fusel oil. After a screening design, the two most appropriate lipases were assayed on a packed-bed system, achieving high conversion rates (90–93%) and productivities of isoamyl stearate up to 3144 mmol g −1  min −1 , which can be used as a substitute to fossil-derived lubricants.
