حمض الأوليك هو أحد الحموض الدسمة التي تعرف بأوميغا-9 و الذي يوجد في العديد من المنتجات النباتية و المنتجات الحيوانية و يتواجد على شكل غليسيريدات ثلاثية (استرات لحمض الأوليك). تم في هذا البحث عزل و تنقية حمض الأوليك بدرجة عالية من النقاوة وصلت حتى 99٪ من الأحماض الدهنية المستخلصة من زيت الزيتون و زيت الذرة و زيت النخيل بمردود وصل إلى 87% من نسبته في الزيوت المستخدمة و ذلك عن طريق استخدام البلورة باليوريا بالإضافة إلى البلورة الانتقائية بالتبريد. كما تم استخدام الكروماتوغرافية الغازية (GC-FID) من أجل التحليل الكمي المباشر لحمض الأوليك و الأحماض الدهنية الأخرى.
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 degree 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.

In this article, a polyester amide was synthesized from oleic acid. This polymer is a biodegradable and thermoplastic polymer, with wide medical and biological applications due to its being compounds with a linear structure. The polymer structure has
been confirmed. Output using spectroscopy methods known as 1H-NMR, and FT-IR spectroscopy. And we obtained this polymer with a good yield (78%).
This research was conducted at the Faculty of Agriculture, Department of
Food Science laboratories to isolate lactic acid bacteria from some Syrian milk
products (milk, yogurt, cheese) and determine some morphological,
physiological characteristic and the ability of these isolates to ferment sugars.
أجري هذا البحث في مخابر كلية الزراعة بجامعة الفرات قسم علوم الأغذية وفي مخابر هيئة الطاقة الذرية بدمشق وقد هدف إلى عزل وتعريف بعض سلالات بكتريا حمض اللبن من الحليب الخام للنوق والماعز الشامي بالإضافة إلى دراسة بعض الخصائص الكيميائية والتصنيعية للسلالات المعزولة وذلك في عامي ( 2010و 2011)
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.
Phosphoric acid is one of the most important products in
chemical industry, where it is used in different industries,
such as food and fertilizer industries and so on .
This study focuses on the preparation of phosphoric acid
from Syrian phosphate in the laboratory by using the
hemihydrate method , and determines the best optimal
conditions for preparing this acid using this method .
