Oleic acid is a fatty acid known as omega-9, which is found naturally in many plant
sources and animal products and is found in the form of tri-glycerides (oleic acid esters). In
this research, the oleic acid was isolated and purified with a high d
egree of purity up to
99% of the fatty acids extracted from olive oil, corn oil and palm oil with a yield of at least
87% of its percentage in the oils used by the use of crystalline urea as well as crystalline
selective cooling . GC-FID was also used for direct quantitative analysis of oleic acid and
other fatty acids.
Terebinth trees have been occupying a good part of the mount of Syrian
(abed elaziz, pelass). The Pistacia atlantica fruit, rich in oil, is used by local
inhabitants in many ways, few studies investigation of the P. atlantica fruit oil
of Syria ha
s been carried out,This study investigates the protein, ash, crude oil
and oil composition of P. atlantica with respect to total phenol, iodine value and
saponification value, in order to classify it among the other known edible oils
thenafter compare the oil composition with the oils of other Pistacia species.
The fruit of P.atlantica appears to be rich in oil. The major fatty acid in the
sample studied are oleic, linoleic, our results show that. The oil has a higher
content of unsaturated FA (oleic + linoleic = 72%). The oil can be classified as
an oleo-linoleic vegetable oil. The biochemical data showed an elevated MUFA
content (50-48%) which may constitute an important property against certain
pathologies for its nutritional and preventive virtues.
The aim of this research is to show that the insaturated fatty acids and their
esters acquire quite interesting surfactant properties when they are sulfonated
with SO٣ or HSO٣Cl.
They are of great interest by virtue of being derived from renewable
natural
source in addition to their surface tension lowering, foaming power, rapid
biodegradability and excellent performance in hard water. Yet, they achieve an
improvement in soap behaviour in hard water. Therefore this type of
surfactant can form a particularly effective synergistic system.
