Abstract:

Fusel oil (FO), a byproduct of sugarcane fermentation rich in isoamyl alcohol, can react with fatty acids (FA) to produce isoamyl oleate (AO ISO), a non-toxic biolubricant. This study explores AO ISO synthesis via esterification catalyzed by lipase B from Candida antarctica (CALB) immobilized on a cashew apple bagasse lignin-magnetic nanoparticle composite (Lig NMP). Lignin extracted from cashew apple bagasse was combined with magnetic nanoparticles, and CALB was immobilized on this composite. Using a 40 mg/mL biocatalyst concentration, esterification with oleic acid and fusel oil at various molar ratios (1:1, 1:2, 1:5) was conducted at 40°C and 150 RPM for 24 hours. Optimal conditions esterified FAs from vegetable oils, achieving near or above 80% conversion and high AO ISO purity. Gas chromatography confirmed these results, showing a 26% improvement over free CALB reactions, with canola and olive oil FAs yielding the highest purity and conversion. This process suggests a sustainable method for biolubricant production using industrial byproducts.
