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.
