يحتوي 2-متيل كينولين ( الكينالدين ) هدروجينات زلوقة يمكن أن تدخل في تفاعلات هامة كالإضافة الألدولية و تفاعل مانخ. تم تحضير الكينوفتالون من تفاعل الكينالدين مع بلا ماء حمض الفتاليك بحضور كلوريد الالمنيوم اللامائي، تم تحضير مشتقات إيمينية من تفاعل الكينوفتالون مع كل من هيدركسيل أمين و فنيل هيدرازين ثم أجريت ديأزة لا مائية للمركبات الناتجة. تم تحضير أربعة مشتقات للكينو فتالون و تنقيتها و التأكد من بنيتها بالطرائق الطيفية (H1NMR,IR, MS).
Quinaldine includes shifting hydrogenes which might be involved in
important reactions as the condensation and Mannich reactions.
Quinophtalone has been prepared through the reaction of quinaldine with
phtalyic anhydride in the presence of aluminium chloride anhydrous
Imines derivatives have been prepared through the reaction of
Quinophtalone with hydroxideamine and phenyl hydrazine and then
diazotion anyhydride has been done to the resulting compounds.
The prepared compounds were characterized by ( H1NMR,IR, MS)

يعد الميتانول و الإيتانول من أكثر المحلات شيوعاً، و بما أن درجة غليانها أقل من مئة
درجة مئوية فإنها تتطاير بشكل سريع. و على سبيل المثال، يستعمل الميتانول في تصنيع
الأصبغة و العقاقير و العطور.. و هو شديد السمية، لذلك من الضروري تطوير محسات لكشفه.

In this work the electrochemical behavior of Para-nitro aniline
and metoxy benzealdehyde was studied by cyclic voltammetric
method on glassy carbon electrode in alkaline medium . It was
found that the Para- nitro aniline needed five electrons to reduce to
the azo group.
Five derivatives of Formazn (FM1–FM5) were prepared through reaction between
benzaldehydphenylhydrazone with five diazonium salts by a reaction ratio of 1:1 in
alkaline medium. The hydrazone was prepared through the reaction between
phenylhydrazin
Three samples of alumina_zirconia mixed oxid AL2O3_Zr2O4(1;0.25;0.1) mole ratio
based on oxides were prepared by sol-gel precipition method. The system AL2O3_Zr2O4
was obtained by mixing tow gel of alumina and zirconia precipited from aqueous solut
Some samples of alumina supporting with sulfate ions and molybdenium were
prepared by impregnation method. Supported samples were calcinated at 550°C for 6h.
Presence of sulfate ions and molybdenium lead to decreasing of the specific surface area o
