Abstract AR
يتضمن البحث تخليق قواعد شيف الحامضية أو القاعدية و الحاوية على مجاميع أو كزيمة أو فينولية أو مجموع كليهما.
كما يحوي البحث على اوكزيمات سين و أنتي المشتقة من -2 استايل بردين و مركبات أخرى و بطرق قياسية.
لقد وجد أن التسحيح المجهادي هي طريقة دقيقة، سريعة و بسيطة في تقدير pKa للأحماض او pKa للأحماض القرينة و عند استعمال مادتي NaOH و HCI كمواد مسححة على الترتيب.
الطرقة المذكورة طبقت بنجاح في تعين ثوابت التأين للأيمينات في مدى من درجات الحرارة المطلقة و المحصورة بين 333-233.
ذلك شجع الباحث بالدراسة الثرمو ديناميكية و لتفاعلات تأين الأمينات في مذيب % 10 ايثانول مع مناقشة و تقسير هذه المتغيرات.
Abstract EN
The project was concerned with synthesis of mono acidic or diacidic Schiff bases having oxime or phenol groups or a combination of them respectively.
Other syn and anti oximes were derived from 2-acetyl pyridine, and others included and synthesized by a standard methods.
Potentiometric titration was found previously, an accurate, simple and fast method for determination of pKa for acids or pKa for acid conjugates of Schiff bases using NaOH and HCl titrant respectively.
This method was applied successfully in this investigation for the determination of ionization constants of imines in a range of temperature (293-313)K.
This encourage the workers in this study to deal with thermodynamic parameters such as ΔG◌ْ , ΔH◌ْ and ΔS◌ْ for the ionization reactions of imines at 10 % ethanol solvent as interpreted and discussed.
