تم في هذا البحث حساب ثوابت تفكك حامضي لعدد من قواعد شيف المشتقة من -4،6- ثنائي مثيل-أمينو بيرميدين في محيط (50 %) حجم / حجم دايوكسان / ماء في 0.003 (X=H,OH;Y=H,OH,OCH3; Z=H,OH حيث أن ΔS0 ، ΔH0 ( ، ΔG0 و في ثلاث درجات حرارية مختلفة مجهاديا.
و كذلك حسبت الطاقات الثرموداينميكية (KCl مولاري و العدد الموجي (سم -1) لاهتزاز المطي لمجموعة الهيدروكسيل في طيف الأشعة pKa و تم التوصل لعلاقة خطية بين تحت الحمراء.
Abstract EN
Acid dissociation constants of some Schiff bases derived from 4, 6-dimethy l 2-amino pyrimidine of the type (1) in 50% V/V dioxane-water mixture in 0.003M KCl, at three different temperatures were determined potentiometrically.
The thermodynamic energies were calculated and a good linear correlation was obtained between pKa and IR OH.
Stretching frequencies.
