摘要: BACKGROUND Lubricants manufactured conventionally from non-renewable mineral oil resources are not biodegradable and liable to cause adverse environmental impacts. Biodegradable vegetable oils present a promising lubricant feedstock alternative. Waste cooking (WCO), which otherwise finds no immediate potential utilization can be successfully used synthesize bio-lubricant. A novel synthetic method was developed by using the two-step process of C. rugosa lipase-mediated hydrolysis WCO free fatty acids (FFA) followed Amberlyst 15H esterification FFA with octanol. The octyl esters produced desired biolubricant. RESULTS The effect different physico-chemical parameters like temperature, catalyst loading, agitation speed, molar ratio octanol:FFA presence desiccants on reaction examined. optimum conditions get maximum yield biolubricant in minimum time were, = 3:1, temperature 80 °C, 2 g desiccant (preferably silica gel powder) 50% weight FFA. Fourier transform infrared spectroscopy confirmed that product formed ester. CONCLUSION Biolubricant (octyl esters) prepared efficiently developed. This approach represents viable means producing lubricants wastes renewable nature an alternative feedstocks. Copyright © 2012 Society Chemical Industry
