يركز هذا البحث على ناحية بيئة واقتصادية، حيث يعتمد على استخدام عشبة زهرة النيل الضارة كمادة فعالة في انتاج البوليمير الحيوي بولي هيدروكسي بوتيرات "polyhydroxybutyrate PHB" بواسطة البكتريا "Bacillus subtilis". تمت معالجة العينات وتهضميها لاستخلاص البوليمير بولي هيدروكسي بوتيرات PHB)) وذلك باستخدام طريقة الكلوروفورم. نفّذت بعض الاختبارات لتؤكد هوية هذا البوليمير كقياس درجة انصهار المنتج ودراسة المجموعات الوظيفية لـ PHB المستخلص باستخدام مطيافية الأشعة تحت الحمراء (FTIR). بينت النتائج تطابق اختبارات البوليمير المستخلص من عشبة زهرة النيل مع اختبارات البوليمير PHB القياسي مما يبين أهمية هذا البحث في التوصل لطريقة للتخلص من هذا العشب الضار الذي يعد مشكلة بيئية وعبئ اقتصادي كبير عن طريق استثماره في انتاج البوليميرPHB الحيوي.
This research focuses on an environmental and economic aspect, as it depends on using the harmful water hyacinth weed as an effective material to product the biopolymer "polyhydroxybutyrate: PHB" by Bacillus subtilis. The samples were processed and digested to extract the polymer polyhydroxybutyrate (PHB) using chloroform method. Some tests were carried out to confirm the identity of this polymer, such as measuring the melting point of the product and studying the functional groups of the extracted PHB using the Fourier-transform infrared spectroscopy (FTIR). The results obtained by the extracted polymer from the water hyacinth weed showed conformity to the referential PHB polymer tests, which shows the importance of this research in determining a way to get rid of this harmful weed, which is an environmental problem and a large economic burden by investing it in the production of biopolymer PHB.

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%).
The transesterification reactions of Cotton seed oil with Methanol using
potassium hydroxide as catalyst by Reactive Distillation column, were studied.
The ester preparation involved a transesterification reaction, followed by
purification.
This work represent synthesis of new benzoxazines polymers based on

The aim of the present study is to prepare extended hard capsules of furosemide using
Eudragit RL, Eudragit RS and Ethyl cellulose individually and in different ratios (6,8,12 and
15%). The granules were prepared by wet granulation using isopropyl
alcohol as a
granulating agent and then filled into capsules. The influence of different concentrations and
type of polymer was studied. The prepared capsules assessed for their physicochemical
properties and in-vitro drug release studies. In vitro release data show that Ethyl cellulose
has more retardation than Eudragits, and Eudragit RS retards drug more than Eudragit RL
does. Furthermore, higher concentration of polymer tends to more retardation than lower
concentration.
Sweeteners are used as alternatives of Sugar because of their slow

This research presents the influence of ultrasonic on th
e sorbitol synthesis,
starting from Glucose by implementing hydrogenation using Lithium
Aluminum Hydride. The result we have reached by using the ultrasonic as
compared with mechanical mixing or other method have lead us to two
conclusions:
The first was that we have obtained almost the same quantity of the sorbitol.
The second was that by using ultrasonic, micelles of colloid Aluminum
hydroxide were accumulated. This accumulation resulted in an easy separation
by purification, which eventually lead to a super pure sorbitol solution.
We hope that these results will be useful for the Crystallography science.
