Abstract

In this work, two different neopentyl glycol (NPG) esters have been synthesized from NPG with 10- undecylenic acid (UDA) and calophyllum fatty acid (CFA) by the esterification process by using para toluene sulfonic acid as a catalyst. The esterification reaction progress has been determined by collecting measured water by using the Dean Stack apparatus. The prepared ester structures have been characterized by NMR, IR and the general physico-chemical behaviors such as density, viscosity, flash point, pour point and copper strip corrosion were determined. Moreover, these prepared ester properties have been compared to commercial ISO VG grade lubes.
