Hydrogenation reaction with n-heptane on Pt/Al2O3 catalyst was investigated under the steady state condition in a fixed bed reactor. The catalyst was prepared under a variety of conditions, but the one chosen was non-acidic that is not considered a hydrocracking catalyst. The main objective was to vary the selectivity of n-heptane as a function of reaction variables es...

Catalyitic reforming is one of the refinery processes in catalyst conversion that results to anincreases in octane number of naphtan which leads to production of gasoline with higher octanenumber. Hydrocarbons with high octan number that are produced in reforming process are as;aromatics, paraffins, isomers and etc.Not only Aromatics are used as fuel for motors but they are also useful in petro...
The new trans-[Pt(4-mpy)2Cl4] (1) complex (4-mpy is 4-methylpyridine) was prepared from the reaction of H2PtCl6.6H2O with 4-methylpyridine in methanol. Synthesized complex was thoroughly characterized by elemental analysis, IR and 1H-NMR spectroscopy.Elemental analysis data (C, H, N) support the general composition of the title complex and the structure have been established by single-crystal X...
در این کار تحقیقاتی ابتدا مطالعه سینتیک واکنش پیریدین و 2 کلر پیریدین با کمپلکس پلاتین (ii) به فرمول p-tol)2 (sme2)2])pt]در دماهای 30،20،15،5 و 40 درجه سلسیوس بررسی گردید. که بدلیل سرعت زیاد واکنش محاسبه پارامترهای سینتیکی غیر میسر بود لذا کار ترمودینامیکی جانشینی سه لیگاند از پیریدین و مشتقات آن (2 کلروپیریدین و 2 برموپیریدین) در سه حلال (دی کلرو متان، استن و متانول) در دستور کار قرار گرفت. ب...
Introduction: The current study investigated the combination of high Z atoms (iodine-, platinium-based drugs) with using low energy irradiation (120kvp) in Anaplastic Thyroid cancer cells.Materials and Methods: For this purpose, eight groups were designed: control (CNT), different concentrations of Iodine contrast media (ICM), irradiation with various doses, Cis-platin (CDDP) with different c...
