Abstract AR
يشمل البحث على تفاعل توتومرية نوع اينول↔ كيتو بمركب بنزلديين –اورثو هايدروكسي انيلين المرقم (I) بجانب دراسة ثرموديناميكية التفاعل بالحالة السائلة.
اثبتت النتائج توافر نسبة الاينول و المدعمة بالقيمة الموجبة للدالة الثرموديناميكية G∆ و بقيمة 4.4 كيلو جول مولֿˡ .
كما تضمن البحث حساب المتغيرينD ∆ و S∆ و بمعدل قيم سالبة بلغت 1.1- كيلو جول مولֿˡ و -18 جول.مولֿˡ و -18جول.مولֿˡ .منطقة ֿˡ على الترتيب , و ان هذه القيم تدعم حصول تفاعل التوتومرية.
أخيرا تضمن البحث دراسة مقارنة لتفاعل التوتومرية بالمركب (I) في الحالتين السائلة و الغازية.
Abstract EN
The study deals with the tautomerism reaction of type enol keto in benzylidene-o-hydroxyaniline (I), beside the thermodynamic study of such reaction in solution state.
The results show the enol content in molecule (I) is predominant as evident from the positive value of average ∆G function of value 4.4 kJ.mole-1.
Moreover, others calculated ∆H and ∆S parameters have an average negative values of about -1.1 kJ.mole-1 and -18.0 J.mole-1.K-1 respectively, these support the tautomerism reaction.
Finally a comparative study between the tautomerism constant values in solution and gaseous states for the reaction stated above, is given.
