[ 1 ] - Nano-CrY zeolite as a new and reusable catalyst for synthesis 2-aryl-1H-benzothiazoles
The Nano-CrY zeolite synthesized and characterized by Fourier transfer infrared (FT-IR), X-ray diffraction (XRD),and Scanning electron microscopy (SEM).The result show that nano catalyst prepared with mainly particles size about 30-80 nm .The XRD show the structure of the zeolite does not collapse. This Nano-CrY zeolite has been used as new, and nontoxic catalyst for catalyzes of synthesis of 2...
[ 2 ] - Efficient Oxidative Dehydrogenation of Dihydropyrimidinones and Thiocyanation of Aromatic Compounds Using 1,1,2,2-Tetrahydroperoxy-1,2-diphenylethane as the Oxidant
A new, efficient and mild approach for the oxidative dehydrogenation of dihydropyrimidinones and thiocyanation of aromatic compounds using 1,1,2,2-tetrahydroperoxy-1,2-diphenylethane (THPDPE) as a terminal oxidant was developed. Initially, various substrates bearing different electron-donating and electron-releasing functionalities were synthesized and next under the optimized reaction conditio...
[ 3 ] - بررسی فیتوشیمیایی و فعالیت آنتی اکسیدانی اسانس مریم گلی ارغوانی بومی ایران (Salvia multiculis vahl)، و کاربرد آن در پایداری اکسایشی روغن آفتابگردان
مقدمه هدف شناسایی ترکیبات و سنجش فعالیت آنتی اکسیدانی عصاره آبی و اسانس روغنی گیاه مریم گلی ارغوانی بومی ایران و کارایی آنها در پایداری اکسیداسیون روغن آفتابگردان می‌‌باشد. مواد و روش‌‌ها عصاره و اسانس به ترتیب از روش خیساندن و اسانس‌‌گیری توسط دستگاه کلونجر به روش تقطیر با بخار تهیه شدند. میزان ترکیبات فنلی عصاره و ترکیبات فرار اسانس به ترتیب به روش فولین-سیکالتو و دستگاه گازکروماتوگراف متصل ش...
