Low-cost chicken waste fat, with a high content of palmitic acid (saturated fatty acid) and oleic acid (unsaturated fatty acid) was used for biolubricant production. The effects of different reaction parameters on the fat transesterification reaction using potassium hydroxide to form fatty acid methyl esters were investigated. In this study, the methyl esters from chicken waste fat were chemically modified to produce hydroxyl ethers (biolu-bricants) through epoxidation, followed by the ring-opening reaction of the epoxides with isoamyl alcohol in the molar ratio of 3:1 (alcohol:methyl esters) using the acid catalyst p-toluene sulfonic acid. The biolubricant obtained after the ring-opening of the methyl epoxides exhibited higher oxidative stability (OS) (18 h) than that of the biodiesel (3.85 h). The viscosity index of the biolubricant was found to be 295.32. The tribological performance of the biolubricant was enhanced by the addition of TiO2 (0.05% w/v). The biolubricant with 0.05% TiO2 led to a 25% reduction in friction coefficient and also enhanced the viscosity by 1.1-fold. Thus, TiO2 is suggested as a good antifriction property enhancer and viscosity modifier for the chicken waste lubricant. In summary, the chicken waste fat can be considered a feasible alternative to formulate biolubricants that match the physico-chemical and low-temperature properties of commercial hydraulic oils.
