Assessing Nitration Products of Benzene Derivatives Using TLC Analysis

Benzene nitration: validation of heterogeneous reaction models

The film and the Danckwerts penetration models were used to model the heterogeneous liquid–liquid reaction of benzene nitration. Analytical solutions were developed for both models considering a pseudo-first order reaction. Models were confronted with experimental results showing good predictions in the intermediate reaction regime (0.3<Ha< 2). Profiles of both models were evaluated confirming ...

analysis of ruin probability for insurance companies using markov chain

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...

Application of topological and physicochemical descriptors: QSTR analysis of the toxicity of benzene derivatives

Rate of Nitration of Benzene with Mixed Acid

The rates of nitration of benzene by nitric acid in mixed acid to produce mononitrobenzene have been measured in well-emulsified reaction mixtures in the temperature range from 34’ to 54°C. The acid-phase compositions ranged from 1.6 mole % nitric acid and 27 mole % sulfuric acid to 35 mole % nitric acid and zero % sulfuric acid; the organicphase composition ranged from 4 to 95 mole ’ % benzene...
