| چکیده | ||
| کاتالیست نانو مغناطیس اسیدی اصلاح شده (SiO2/Fe3O4/SO3H) به روشی ساده بدست آمد و برای تهیه ایمیدازول‌های سه استخلاف 2و4و5- ، بوسیله ی سه جزء بنزیل، آلدهید‌ها و آمونیوم استات که به عنوان منبع تامین کننده ی آمونیا هست، به کار گرفته شد. بازده بالا بدون از دست دادن کارامدی، بازیابی آسان بوسیله ی آهنربای خارجی و استفاده چندین باره از کاتالیست بدون کاهش محسوس در بازده از مزایای این کاتالیست SiO2/Fe3O4/SO3H می‌باشد. تحمل پذیرش مقدار زیادی اسید روی سطح لایه مغناطیسی منجر به فعالیت بیشتر کاتالیست و در نتیجه بازده ایمیدازول سه استخلافی افزایش مییابد. نانو ذره مغناطیسی لایه نشانی شده‌ی عامل دار بوسیله ی دستگاه‌های FT-IR، XRD، EDS، TGA، VSM، TEM تحت شناسایی قرار گرفته و تأیید شد | ||

| چکیده [English] | ||
| Modified nanomagnetic acid catalyst SiO2/Fe3O4/SO3H was synthesized in simple method and used for synthesizing 2,4,5-tri substituted imidazole by combining three components such as benzil, aldehydes and ammonium acetate of which the last component was as an ammonia source. High yield of tri-substituted imidazole without significant loss of efficiency and easy recovery by an external magnetic field and several times of reusability with less deterioration are advantages of SiO2/Fe3O4/SO3H catalyst. A large amount of acid existing on the surface of the magnetic layer leads to more activities of the catalyst and as a result, the yielding of tri-substituted imidazole increases. The acidic functioned nanomagnetic core-shell catalyst was approved as per Fourier transfer infrared (FT-IR), X-ray diffraction powder (XRD), Energy dispersive X-Ray spectroscopy (EDS), Thermal gravimetric analysis (TGA), Vibrating sample magnetometer (VSM) and transmission electron microscopy (TEM). | ||
