Abstract

Biodegradable esters have been synthesised using Polyols such as 2‐methyl‐2‐n‐propyl 1,3‐propane diol, 2,2‐di methyl 1,3‐propane diol, 1,1,1‐[tris] hydroxyl methyl propane, 1,1,1‐[tris] hydroxyl methyl ethane and carboxylic acids (C6‐C12) both pure and their mixtures with indigenous ion exchange resin (Indion‐130) catalyst. The products were characterised for their physico‐chemical properties and were evaluated for their lubrication performance. These were then compared with VG‐22 grade fire resistant hydraulic fluids (FRHFs).The products were found to have good potential for use as a base stock for formulations as FRHF of VG‐22 grade.
