Abstract : Biolubricants can also be manufactured from fusel oil. In this case, longer chain acid compounds (fatty acids from, for example, hydrolysis of plant oils) should be used in the esterification reaction. The process can be carried out by acidic (Özgülsün et al., 2000) or enzymatic catalysis (Fig. 9.1). The drawback of acidic catalysis is that acid traces may remain in the product, which causes corrosion during utilisation. By applying enzymatic catalysis (e.g. lipase), this can be avoided. The biolubricants obtained are not only derived from natural renewable sources (biomass), but can also be degraded biologically
