Abstract :
نانوذرات مغناطيسي MgFe2O4 يك كاتاليزگر فعال، پايدار ويك كاتاليزگر قابل بازيافت براي اكسايش الكل ها است. اكسايش انواع الكل ها مورد آزمايش قرار گرفت ومحصول مربوطه با بازده بالا به دست آمد. واكنش در آب در حضور اكسون در دماي اتاق و يا هيدروژن پراكسيد در دماي 60 oC به عنوان اكسنده انجام شد ساختار و مشخصه كاتاليزگر تهيه شده با تكنيك هاي IR ، XRD ، SEM و ICP مورد بررسي قرار گرفت. همچنين كاتاليزگر بدون از دست دادن فعاليت، به آساني تا 7 بار بازيافت و بكار گرفته شد. كلمات كليدي: كاتاليزگر نانو مغناطيس، منزيم فريت، اكسايش، الكل، اكسون، هيدروژن پراكسيد.
Abstract :
Nanomagnetic MgFe2 O4 is an active, stable, and reusable catalyst for the oxidation of alcohols. Te oxidation of various primary and secondary alcohols has been examined and related corresponding products were obtained in good yields. Te reactions were carried out in the presence of water as solvent and oxone (at room temperature) or H2 O2 (at 60 ?C) as an oxidant. Te catalyst was investigated by X-ray powder difraction, scanning electron microscope, inductively coupled plasma and infrared techniques. Furthermore, the catalyst could be easily recovered and reused up to 7 runs without loss of activity.
