تتضمن الدراسة اصطناع مركبين فوسفوريين عضويين يملكان الجسر P-NH-c لهما الصيغ الكيميائية التالية: (PhO)2P(O)-NH-C(CH3)=CH-CN اختصاره PCNO, و المركب (PhO)2P(S)-NH-C(CH3)=CH-CN و اختصاره PCNS , الذين تم اصطناعهم في وسط من الاسيتونتريل وبوجود قاعدة قوية هي هيدريد الصوديوم NaH من المركبين ثنائي فنيل كلورو الفوسفات (PhO)2POCl و المركب ثنائي فنيل كلورو تيو الفوسفات (PhO)2PSCl على التوالي , درست بعض الخواص الفيزيائية و الكيميائية للمركبين المصطنعين مثل درجة الانصهار , الانحلال وكما سحب بعض الطيوف الهامة مثل طيف IR و طيف NMR,استخدم المركبين في استخلاص شوارد النحاس الثنائية من وسط الكبريتات , درس عامل توزع أيون النحاس Dcu بين وسط مائي من و وسط عضوي يحتوي على تراكيز مختلفة من المركبات الفوسفورية العضوية المحضرة سابقا" , كما درس عامل توزع أيون النحاس بدلالة تغير قيمة الpH (pH= 4---6) عند تركيز ثابت من المستخلص المستخدم المذكور سابقا" و استخدم جهاز السبيكتروفوتومتر لحساب تراكيز النحاس بالاعتماد على الامتصاصية , و جرى مقارنة الاستخلاص بين المركبين السابقين .
The study addresses the synthesis of two organic phosphoric compounds that have
the P-NH-c bridge, They have the following chemical formula (PhO)2P(O)-NH-C(CH3)=CHCN
( abbreviated as PCNO) and The compound (abbreviated as PCNS) The compound
were synthesized in the center of acetonitrile and having a strong base of sodium hydride
NaH by Diphenyl chloro phosphate (PhO)2POCl compounds and Diphenyl chloro thio
phosphate (PhO)2PSCl compound Respectively . Some of the physical and chemical
properties of the synthetic composites, such as the melting point, dissolution , and the
withdrawal of some important spectra such as the IR spectra and the NMR spectra were
used in the extraction of the copper(II) Ions from the of medium sulphates, Lesson of
Partition Coefficient Copper Dcu between aqueous medium of organic medium containing
different concentrations of organic phosphorus compounds prepared previously. Partition
Coefficient copper(II) ion distribution was studied in terms of the change in the value of
PH (PH = 4 --- 6) at the constant concentration of the extract used previously .The
Spectrophotometer for calculating copper concentrations was used Depending on absorption ,
and the two previous components were compared .

Kinetic studies were carried out on the reaction between 2-Methyl 1,5
diaminopentane and dimeric fatty acids in melt phase. The reaction was
performed at 113, 130, 140, 155, and 164 ºC and followed by determining the
acid value of the product .The
A sensitive, simple, selective spectrophotometric method has been developed for determination Cobalt (II) with 1-(2-pyridylazo)-2 naphthol (PAN). This method ralies on the formation of stable red colored complex at pH=4.1 which has an absorption maximum at 580nm.
A new carbon paste electrode (CPE) for Co2+ ion modified with
complex of Cobalt(II) with 1-(2-pyridylazo)-2-naphthol (PAN) as
electroactive 84aterial was prepared. The best performances were
obtained by carbon paste electrode with the composition Graphit
powder (47%), DOPH as plasticizer (47%) and Co-PAN as
electroactive material (6%)
