The invention relates to preparation of epoxy karanja oil, epoxy karanja fatty acid methyl esters and their acylated derivatives. Accordingly, karanja oil and karanja fatty acid methyl esters were epoxidized using performic acid method. Karanja oil and its fatty acid methyl esters were also hydroxylated to prepare their acyloxy derivatives (C3, C4 & C6). Both the epoxy and acyloxy derivatives of karanja oil and its methyl esters were characterized by 1H NMR and IR studies. The products were evaluated for Acid Value (A.V.), Hydroxyl Value (H. V.), Iodine Value (I. V.), viscosity, Viscosity Index (V.I.), pour point, flash point and copper strip corrosion and lubricant properties like oxidation stability, air release value, evaporation loss, rust prevention characteristics, hydrolytic stability, foam stability and load carrying capacity and found to be potential base stocks for hydraulic, metal working fluids and other industrial fluids.
