چکیده انگلیسی
Synthesis of environmental-friendly chemicals attracts high attention nowadays, especially when naturally occurring compounds and industrial side-products are utilized. This paper reports for the first time on biolubricant (isoamyl oleate) production via continuous enzymatic reaction in microfluidic reactors (H-Cubeâ¢, X-Cubeâ¢). The proposed esterification was catalyzed using Novozym 435 enzyme, while substrates used were renewable raw materials: oleic acid and isoamyl alcohol. The latter is a main component of fusel oil, the by-product of bioethanol technology. The aim of this investigation was to evaluate the feasibility of the above-mentioned bioconversion in solvent-free media, considered as a cleaner way ahead. The successful applicability of miniaturized, continuous flow reactors for the biocatalytic reaction was demonstrated since isoamyl oleate could be obtained as long as 144 h in the H-Cube⢠without any significant loss of enzyme activity. The highest conversion (98%) was achieved in X-Cubeâ¢. The results indicated that biocatalysts loading, residence time of reactants and dewatering of reaction mixture are important parameters and facilitate improved process efficiency.
