In this study, the chemical conversion of catfish fat (CFF) into bio-based oils using the cavitation technique has been carried out. The influence of parameters on the reaction yield, including inlet pressure, amount of reactant, temperature, and time were investigated. The results obtained have demonstrated the outstanding efficiency of applying the cavitation technique to the chemical synthesis process. The optimum conditions of ring-opening reaction of epoxy catfish oil (ECFO) were as follows: 60 psi, the molar ratio of iso- propanol/epoxy ring of 1.75/1, 75°C, time of 7 min, and the yield reached 91.3%. The results of FT-IR, 1 H-NMR, and 13 C-NMR analysis showed that the chemical conversion of double bonds (C═C) of CFF were converted to functional groups of hydroxyl and ether in polyol catfish oil (CFO) products through the intermediate stage of the formation of the epoxy ring. The results showed that the polyol CFO has better operating conditions at low temperature, higher viscosity, viscosity index, and oxidation stability than other oils, and the biodegradability of bio-polyol CFO was much higher than that of SN500 mineral base oil. Polyol CFO has not only been used as a substitute for mineral base oils but also as an eco-friendly green product.
