Abstract AR
حضرت مركبات البايروميلت ثنائية الايميد [VII] عن طريق تفاعل ذي خطوتين، من ثنائي انهدريد البايروميليتك المقابل، إذ حضرت حوامض الاميك الجديدة من تفاعل ثنائي انهدريد البايروميليتك مع أمينات مختلفة تحتوي حلقة غير متجانسة باستعمال الاسيتون الجاف مذيبا.
بينما تتضمن خطوة التفاعل الثاني الغلق الحلقي الضمني لجزيئة حامض الاميك بوجود انهدريد الخليك–خلات الصوديوم و بدرجة حرارة (80-90) °C.
أثبتت صحة تراكيب المركبات المحضرة بوساطة قياس درجات انصهارها و تحليل العناصر و أطياف UV - : Vis 1HNMR, FTIR لها.
Abstract EN
The new symmetry pyromellitdiimide [VII] a-c, n were synthesized by two-step reactions from the corresponding pyromellitic dianhydride.
A new symmetrical amic acid [VI] a-c, n was synthesized by the reaction of pyromellitic dianhydride with different heterocyclic amines in dry acetone.
The second reaction step includes intermolecular cyclization of amic acid in the presence of sodium acetate -acetic anhydride system at 850C.
Structures of the synthesized compounds have been ascertained by their melting points, C.

N analysis , UV-Vis, FTIR and 1HNMR spectroscopy.
