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.

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 .
